Research question, purpose statement, hypothesis(es).

Here’s a good example of how to narrow your topic into a good research question:

• Too broad — Rural America
• Narrowed topic — Role of women in rural America?
• Research question — What is the central role of women in today’s farming communities?

If you’re asked to write a proposal before you begin your actual research, the proposal will contain a purpose statement that states in some detail what you want to learn about in your research project; it looks something like this:

• Ex.: “This study will examine the…”

Your purpose statement leads you to write a more refined thesis statement or hypothesis(es), an assertion that you can defend and support with evidence gathered in your literature review and research. Here are some examples:

• Ex.: “In the United States, government regulation plays an important role in the fight against air pollution.” Or, conversely,
• Ex.: “United States government regulation has little effect in the fight against air pollution.”

The type of design selected for your study depends on your research question(s), hypothesis(es), or problem.

You’ll use evidence you’ve gathered in your research to confirm — or reject — your hypothesis.

Thesis and Purpose Statements

Use the guidelines below to learn the differences between thesis and purpose statements.

In the first stages of writing, thesis or purpose statements are usually rough or ill-formed and are useful primarily as planning tools.

A thesis statement or purpose statement will emerge as you think and write about a topic. The statement can be restricted or clarified and eventually worked into an introduction.

As you revise your paper, try to phrase your thesis or purpose statement in a precise way so that it matches the content and organization of your paper.

Thesis statements

A thesis statement is a sentence that makes an assertion about a topic and predicts how the topic will be developed. It does not simply announce a topic: it says something about the topic.

Good: X has made a significant impact on the teenage population due to its . . . Bad: In this paper, I will discuss X.

A thesis statement makes a promise to the reader about the scope, purpose, and direction of the paper. It summarizes the conclusions that the writer has reached about the topic.

A thesis statement is generally located near the end of the introduction. Sometimes in a long paper, the thesis will be expressed in several sentences or an entire paragraph.

A thesis statement is focused and specific enough to be proven within the boundaries of the paper. Key words (nouns and verbs) should be specific, accurate, and indicative of the range of research, thrust of the argument or analysis, and the organization of supporting information.

Purpose statements

A purpose statement announces the purpose, scope, and direction of the paper. It tells the reader what to expect in a paper and what the specific focus will be.

Common beginnings include:

“This paper examines . . .,” “The aim of this paper is to . . .,” and “The purpose of this essay is to . . .”

A purpose statement makes a promise to the reader about the development of the argument but does not preview the particular conclusions that the writer has drawn.

A purpose statement usually appears toward the end of the introduction. The purpose statement may be expressed in several sentences or even an entire paragraph.

A purpose statement is specific enough to satisfy the requirements of the assignment. Purpose statements are common in research papers in some academic disciplines, while in other disciplines they are considered too blunt or direct. If you are unsure about using a purpose statement, ask your instructor.

This paper will examine the ecological destruction of the Sahel preceding the drought and the causes of this disintegration of the land. The focus will be on the economic, political, and social relationships which brought about the environmental problems in the Sahel.

Sample purpose and thesis statements

The following example combines a purpose statement and a thesis statement (bold).

The goal of this paper is to examine the effects of Chile’s agrarian reform on the lives of rural peasants. The nature of the topic dictates the use of both a chronological and a comparative analysis of peasant lives at various points during the reform period. . . The Chilean reform example provides evidence that land distribution is an essential component of both the improvement of peasant conditions and the development of a democratic society. More extensive and enduring reforms would likely have allowed Chile the opportunity to further expand these horizons.

Writing a Statement of Purpose

Of all the different types of text you will have to write in the academic world, the statement of purpose is one of the most difficult, not least because it is about you. We spend our time trying to eliminate ourselves from other academic writing, from research proposals or from term papers. Now you have to write a paper about yourself. Like any other academic genre, a statement of purpose has a logical structure and development, and its purpose is to simultaneously show why you are the best candidate for a given course or grant, and why this course or grant is the most suitable one for you. This page will tell you how to do this. But don't leave it at that: when you have finished, come to the Writing Center and discuss your statement of purpose with us. The resulting revised draft will be even more effective.

Do Answer the Question!

Before you start writing your statement of purpose, look careful at any instructions you have been given. If, for example, you have been asked to specify why you want to study at this university, make sure you answer that question, and that your paragraph starts with a sentence that will signal that you are answering it (e.g."My reasons for studying..."). Do not omit to answer any of the questions you are asked, and consider carefully before providing information you were not asked for. If you have 500 words, they expect you to spend most of them answering their questions, not volunteering other information. Frequently, however, universities do not give any guidance as to what they want, perhaps wanting to test if you are intelligent enough to work it out for yourself. If so, the guidelines below are designed to help you.

Attracting the Reader's Attention

When you write a statement of purpose, you need to remember that you are just one of many, perhaps even hundreds of applicants for your chosen study place. The person who reads your statement will have read dozens of others. If yours does not stand out in some way that shows that you are original, different and interesting - which of course you are (but at the same time not eccentric or peculiar - which you may be, but don't emphasize the fact!), it will be consigned to the heap of also-rans, the people who may get a place if there are some left over at the end.

If a statement of purpose fails to catch the reader's attention, it may be due to one or more of the following problems:

• It starts with flattering comments about the university they are applying for - the person who reads your statement already knows how good their institution is: they don't need you to tell them.
• It provides an entire life history, starting from birth, - by the time you reach the important bit, your reader will have lost interest. Unless your high school days are especially interesting, concentrate on your university career.
• It starts off by explaining exactly how the writer heard about this particular course - unless this information shows something important about you, leave it out.
• It begins by providing personal details that can be found on the résumé, such as age or place of birth.
• It begins by trying to second-guess the reader's thoughts, for example: 'You are probably wondering why a specialist in... should be applying for a place at...' This strategy might possibly work, but it will probably be more effective if you go ahead and answer the question.
• Although they do grab attention, the sort of statements that are least successful are those that use over-theatrical and silly introductions that are inappropriate for an academic environment. If you start with 'I am a really special person', or 'Ever since I was a baby, gazing happily at the world...', you shouldn't be surprised if you get rejected.
• Some statements dive straight into the complex field of the specialist, immediately discussing obscure areas of theory. Remember that while you are expected to show familiarity with your subject, not all readers may be specialists in your chosen field. If they can't understand you, they may not realize how good you are.

Capturing the reader's attention - examples

Look at the following two efforts at starting a résumé and see which you think would be more likely to capture the reader's interest:

I am applying for the Central European University, based on the reputation this University has in the academic community world-wide. I have also spoken to several alumni of your university. I am very interested in admission to the graduate program in Economics. I know that research programs in Economics are very diverse and this is the main reason why I prefer this university.

Recent Moldovan government figures show an alarming 40% increase in mental illness amongst young people in the last ten years. These figures are just one more factor that persuades me that my choice of a career in neuroscience was the right one, and motivates me to study further at Ph.D. level in this field in order to help combat this serious problem.

Sample A has several weaknesses:

• it is too general - one could insert the name of any university
• it does not mention any of the specific features of the university nor does it justify the flattering claim of a 'world-wide reputation'
• it simply says that the university has a good reputation and a range of courses - neither very original nor interesting for the reader
• it does not start by answering the question 'Why economics?' but immediately starts with the more specific question of 'Why economics at CEU

Sample B, in contrast, shows several positive features:

• it grabs the reader's attention with an alarming piece of information
• it starts with a reference to the real world, thus moving from the general to the specific
• it shows that the writer is aware of the link between academe and the real world and has a desire to put theoretical learning into practice
• it very succinctly expresses the link between the applicant's past studies, proposed studies and subsequent career

How to start off

Ideally you need to start with an interesting fact or detail about you, your situation or your interests which makes you appear interesting and intelligent. You might also try a more general truth or saying, then show how this applies to your situation. You may want to quote someone famous who has said something relevant, but if so, keep it short, quote correctly, and make sure that the relevance to your position is absolutely clear. Don't quote for the sake of it.

Do give enough time to creating a good initial paragraph. It is the first thing your audience will read, and first impressions are quickly formed. If your first sentences are dull, irrelevant, eccentric or pompous, or worse still, full of grammatical or spelling mistakes, your reader will quickly form a negative impression which will be hard to dispel.

The Structure of a Statement of Purpose

The word 'purpose' normally means 'what you want to do', however, it has a secondary meaning, which is the quality of knowing 'that you want to do something'. Purpose in this sense means having a direction, and it is essential that your statement of purpose shows that you do have a direction and know both where you are going and how you can best get there. A good statement of purpose will usually have the following structure:

How your studies at undergraduate level and at graduate level, as well as any other work or study experience, has prepared you for the course of study that you wish to take.

Your Proposed Course Of Study

Should be shown to be a logical follow-on from your studies/work to date and to prepare you for your future career.

Your Future Career

Should be something for which your proposed course of study is valuable or essential, and should have some logical connection to what went before.

Of course, you own career may not be as simple as this. Perhaps you started studying biophysics, then later developed a passion for medieval poetry. This is not going to disqualify you, but you need to ask yourself 'why should a university choose me rather that someone who has always been interested in medieval poetry?' If you can answer this question, you have a chance of being considered. If, however, your reader gets the impression have suddenly for no good reason conceived an interest in a field you have never studied before, they may equally assume you will lose interest just as quickly. You best chance usually lies in showing that there is a meaningful progression to your career which is driven by your sense of purpose and academic or professional ambition.

The above model suggests that a statement of purpose should move from your past and present studies, to your proposed studies and finally to your future career. If you want to be innovative, you are not obliged to follow this pattern, but the elements and the connection should be there and should be clear to the reader. Before you start writing, draw yourself a clear structural plan, perhaps allowing a paragraph or so for each stage. Obviously, your past will be much clearer and more detailed than your future, but don't neglect the second and third boxes in the diagram above, or you may look like an eternal student, always hunting for something new to study.

How much detail to provide

1. keep to the word limit.

Universities often provide a word limit or a page limit to guide you. Keep to it. If they say they don't want to read three pages, they mean it. Bear in mind that academics have to do an awful lot of reading, not only of statements of purpose but also of essays and theses. If you can't keep to the word limit for a statement of purpose, they may be worrying that you will write a 450 page thesis when 150 pages was the limit. Writing too much is never a way to make yourself popular. If a limit is given, it is good to set yourself a personal maximum limit of 10-15% less than that. And don't feel you have to fill a word limit. If you have said all you want to in 700 words and the limit is 1000, great! Stop. Don't go looking for verbiage to pack in the spaces.

2. Set yourself section word limits

If you have 800 words, have in mind how many you want to spend on each section of your statement. If you use 750 words describing your studies to date, you will have nothing left for the other sections. By setting yourself rough word limits for each part, you ensure that the statement is balanced.

3. Be selective

With any piece of writing where there is a word limit, you will not have enough space to say everything about everything. This means you have to be selective. You have to gather all the necessary information, look at it and throw away the things which are less necessary. It may hurt not to be able to say that you got top grades in your school for physics (when you're applying to study sociology) but you have to be ruthless. Remember that the ability to evaluate and select what to include and what to leave out is valuable academic skill in its own right, and demonstrating that you have that skill can count powerfully in your favor.

4. Use appropriate language

Obviously you need to show you have a good command of the English language: avoid slang, use vocabulary appropriate to your field and show that you can write a sentence of more than 5 words. At the same time, don't start looking for long words to impress with. If an ordinary word will do, don't go thesaurus hunting for a bigger one, not least because you may use it wrongly.

5. Edit thoroughly

When you have written a first draft, go over it and check whether any of your phrases are wordy or clumsy. Try to re-express them clearly and succinctly. While it is good to use longer sentences sometimes, don't ramble. If your sentence has more than 30 words, read it over and see if it would be better to split it into two. Reading aloud may help you to feel if your ideas are clearly expressed.

Some sample statements of purpose

The following sample thesis statements, though well written and successful, are not perfect and may contain mistakes or weaknesses. They are also not about you. It is not included to show you a model that you can copy but to provide an example of how it has been done by others. You will need to write your own statement ion your own words.

My interest in International Relations and my decision to continue my education in this field is the outcome of my profound interest in Asian studies. Majoring in History of India, during my final year I became especially interested in the sphere of International Relations and Foreign Policy of India, writing my thesis on Indian Foreign Policy during Nehru's Government and Indian-Chinese relations. Two trips to India 1997 and 1998 allowed me to become better acquainted with this country, refine my knowledge of Hindi and collect unique data for my research. This unforgettable experience convinced me that I had made the right choice of study, leading me to apply for a PhD Degree so as to extend my research in this field.

I have so far completed two years of the PhD program at St. Petersburg State University. My dissertation aims at disclosing those problems which still hinder the process of normalization between the two Asian countries, India and China, reflecting on how Indian scholars perceive these issues. Thus my research covers both Regional Studies and field of International Relations as a global world system where these two countries play an important role.

My presentation of a paper on Indo-Chinese Relations in 1980s at the international conference "East Asia - St. Petersburg - Europe: inter-civilization contacts and perspectives on economic cooperation" held in St. Petersburg a year ago gave me the opportunity to meet many outstanding researchers, including my referee, Marcia Ristaino, who encouraged me to continue my studies focusing specifically on International Relations and Regional Studies. For that reason I applied and was accepted to the MA Program in International Relations and European Studies at Central European University in Budapest with a scholarship from Soros foundation. The courses I am taking here will provide me with a sound background in theoretical issues in International Relations.

The reason of why I am applying for another Master's Degree is that the CEU program, despite its theoretical strength, has very few courses directly related to my major interest, Regional Studies and conflict resolution and peacekeeping. For this reason I would like to deepen my practical understanding of International Relations and relate it to a more focused concentration on conflict analysis and resolution through the program of the Carleton University.

I am aware of the high reputation of your school and the excellent Master's program that you offer at the Norman Paterson School of International Affairs. I believe it will certainly help me with my research and career objectives either through work in diplomatic service or at an international organization where I will be able to apply my knowledge and skills obtained through studies at your University.

Courses such as Conflict Analysis, International Mediation and Conflict Resolution and International Organizations in International Affairs will be very helpful for my analyzing of the problems in the South Asian subcontinent and beyond it and will allow me to deeper understand the reasons for numerous interstate and intrastate conflicts that persist in the region. Moreover these courses will be of particular relevance to my career plans which are to find employment with UN or a similar institution in the field of conflict resolution and peacekeeping. The possibility to combine theoretical studies with practical skills in conflict analysis and resolution at the Carleton University will enable me to become a good specialist who will be able to contribute to the common cause of peace in the world. I am eager to become a professional orientalist, as I believe this field of study will always be important in the changing world where Asian countries such as India and China play significant roles in the international arena. MA at the Carleton University would be a precious experience both in terms of my academic and professional career. I hope you will give me the opportunity to realize my ambition.

Having majored in literary studies (world literature) as an undergraduate, I would now like to concentrate on English and American literature. I am especially interested in nineteenth-century literature, women's literature, Anglo-Saxon poetry, and folklore and folk literature. My personal literary projects have involved some combination of these subjects. For the oral section of my comprehensive exams, I specialized in nineteenth century novels by and about women. The relation ship between "high" and folk literature became the subject for my honors essay, which examined Toni Morrison's use of classical, biblical, African, and Afro-American folk tradition in her novel. I plan to work further on this essay, treating Morrison's other novels and perhaps preparing a paper suitable for publication.

In my studies toward a doctoral degree, I hope to examine more closely the relationship between high and folk literature. My junior year and private studies of Anglo-Saxon language and literature have caused me to consider the question of where the divisions between folklore, folk literature, and high literature lie. Should I attend your school, I would like to resume my studies of Anglo-Saxon poetry, with special attention to its folk elements.

Writing poetry also figures prominently in my academic and professional goals. I have just begun submitting to the smaller journals with some success and am gradually building a working manuscript for a collection. The dominant theme of this collection relies on poems that draw from classical, biblical, and folk traditions, as well as everyday experience, in order to celebrate the process of giving and taking life, whether literal or figurative. My poetry draws from and influences my academic studies. Much of what I read and study finds a place in my creative work as subject. At the same time, I study the art of literature by taking part in the creative process, experimenting with the tools used by other authors in the past.

In terms of a career, I see myself teaching literature, writing criticism, and going into editing or publishing poetry. Doctoral studies would be valuable to me in several ways. First, your teaching assistantship program would provide me with the practical teaching experience I am eager to acquire. Further, earning a Ph.D. in English and American literature would advance my other two career goals by adding to my skills, both critical and creative, in working with language. Ultimately, however, I see the Ph.D. as an end in itself, as well as a professional stepping-stone; I enjoy studying literature for its own sake and would like to continue my studies on the level demanded by the Ph.D. program.

Research proposal or statement of purpose.

Second only to the Personal Statement, is your Research/Project Proposal or Purpose Statement, which you can also expect to include in nearly every national scholarship or fellowship application.  And, you can certainly anticipate some variation of this particular kind of statement to be an expected part of your graduate school applications as well.  As with your Personal Statement, it needs to reflect something of you but with a much more specific focus on your academic plans and preparation.  A Purpose Statement will also be relatively short, at most two-pages in length, and is your opportunity to make a well-substantiated case for what you are proposing to do in the future. Most students will find the Purpose Statement, Research or Project Proposal surprisingly comfortable to write as opposed to the Personal Statement because it is expected that your Purpose Statement is written from a largely academic focus.  Your statement should include the following:

• A clear, early (as in the first sentence or two) introduction of what you intend to do and/or study;
• A well-substantiated (through your CV, transcripts, other essays, writing sample, and letters  of recommendation) case for your exceptional preparation for what you are proposing to pursue and/or study;
• A description of the institution, program, department, research group, faculty and resources that you are interested in being a part of and engaging with in your advanced studies.  Note: the more specific, the better.  It is appropriate, perhaps even expected, to name the individual faculty you would like to work with and make every effort to contact those individuals in advance of submitting your application.  Keep in mind that you are making a case for the following:
• Why you have to be at that particular location or institution;
• With whom you must study in order to be most successful in your efforts;
• What resources will support and sustain your efforts (research and lab facilities, archives, special collections, field-work opportunities, etc.

In short, try to convince your reader that what you are proposing to research or work on can only be done in that particular part of the world and that you, simply, must be there to be the most successful. 

As with your Personal Statement, the more time you devote to careful planning, thought, and writing, the stronger your Purpose Statement will be.  Make sure to ask your faculty mentors and advisors to review your Purpose Statement and/or Research Proposal as they will be able to best guide you in refining your subject and even providing you with further contacts and resources.  Give yourself time to revise, edit, and revise some more. 

NOTE: Some national scholarship and fellowship opportunities require an actual Research Essay ( Goldwater  and the National Science Foundation Graduate Research Fellowship ).  In this case, expect to submit a very detailed description of your undergraduate research efforts and how you expect to see the work continue in the coming years.  Successful Goldwater research essays often include graphs, charts, notes and bibliographies to give evidence not only to the quality of the research but also to the quality of the students’ ability to put it in writing. 

The Fulbright U.S. Student Program’s research- and study-grants also requires a similar effort in crafting a highly specific project-proposal based on what an applicant intends to pursue in a foreign country.  The proposal needs to be a specific and targeted articulation on research and project plans while still attending to the Fulbright’s ultimate concern of cultural exchange.

A purpose statement is a vital component of any project, as it sets the tone for the entire piece of work. It tells the reader what the project is about, why it’s important, and what the writer hopes to achieve.

Part 1 Key Elements of a Purpose Statement

When writing a purpose statement, there are several key elements that you should keep in mind. These elements will help you to create a clear, concise, and effective statement that accurately reflects your goals and objectives.

1. The Problem or Opportunity

The first element of a purpose statement is the problem or opportunity that you are addressing. This should be a clear and specific description of the issue that you are trying to solve or the opportunity that you are pursuing.

2. The Target Audience

The second element is the target audience for your purpose statement. This should be a clear and specific description of the group of people who will benefit from your work.

3. The Solution

The third element is the solution that you are proposing. This should be a clear and specific description of the action that you will take to address the problem or pursue the opportunity.

4. The Benefits

The fourth element is the benefits that your solution will provide. This should be a clear and specific description of the positive outcomes that your work will achieve.

5. The Action Plan

The fifth element is the action plan that you will follow to implement your solution. This should be a clear and specific description of the steps that you will take to achieve your goals.

Part 2 How to Write a Purpose Statement Step-by-Step

Writing a purpose statement is an essential part of any research project. It helps to clarify the purpose of your study and provides direction for your research. Here are some steps to follow when writing a purpose statement:

• Start with a clear research question: The first step in writing a purpose statement is to have a clear research question. This question should be specific and focused on the topic you want to research.
• Identify the scope of your study: Once you have a clear research question, you need to identify the scope of your study. This involves determining what you will and will not include in your research.
• Define your research objectives: Your research objectives should be specific, measurable, achievable, relevant, and time-bound. They should also be aligned with your research question and the scope of your study.
• Determine your research design: Your research design will depend on the nature of your research question and the scope of your study. You may choose to use a qualitative, quantitative, or mixed-methods approach.
• Write your purpose statement: Your purpose statement should be a clear and concise statement that summarizes the purpose of your study. It should include your research question, the scope of your study, your research objectives, and your research design.

Research question: What are the effects of social media on teenage mental health?

Scope of study: This study will focus on teenagers aged 13-18 in the United States.

Research objectives: To determine the prevalence of social media use among teenagers, to identify the types of social media used by teenagers, to explore the relationship between social media use and mental health, and to provide recommendations for parents, educators, and mental health professionals.

Research design: This study will use a mixed-methods approach, including a survey and interviews with teenagers and mental health professionals.

Purpose statement: The purpose of this study is to examine the effects of social media on teenage mental health among teenagers aged 13-18 in the United States. The study will use a mixed-methods approach, including a survey and interviews with teenagers and mental health professionals. The research objectives are to determine the prevalence of social media use among teenagers, to identify the types of social media used by teenagers, to explore the relationship between social media use and mental health, and to provide recommendations for parents, educators, and mental health professionals.

Part 3 Section 1: Identifying Your Goals

Before you start writing your purpose statement, it’s important to identify your goals. To do this, ask yourself the following questions:

• What do I want to achieve?
• What problem do I want to solve?
• What impact do I want to make?

Once you have a clear idea of your goals, you can start crafting your purpose statement. Your purpose statement should be a clear and concise statement that outlines the purpose of your work.

For example, if you’re writing a purpose statement for a business, your statement might look something like this:

“Our purpose is to provide high-quality products and services that improve the lives of our customers and contribute to the growth and success of our company.”

If you’re writing a purpose statement for a non-profit organization, your statement might look something like this:

“Our purpose is to improve the lives of underserved communities by providing access to education, healthcare, and other essential services.”

Remember, your purpose statement should be specific, measurable, and achievable. It should also be aligned with your values and goals, and it should inspire and motivate you to take action.

Part 4 Section 2: Defining Your Audience

Once you have established the purpose of your statement, it’s important to consider who your audience is. The audience for your purpose statement will depend on the context in which it will be used. For example, if you’re writing a purpose statement for a research paper, your audience will likely be your professor or academic peers. If you’re writing a purpose statement for a business proposal, your audience may be potential investors or clients.

Defining your audience is important because it will help you tailor your purpose statement to the specific needs and interests of your readers. You want to make sure that your statement is clear, concise, and relevant to your audience.

To define your audience, consider the following questions:

• Who will be reading your purpose statement?
• What is their level of knowledge or expertise on the topic?
• What are their needs and interests?
• What do they hope to gain from reading your purpose statement?

Once you have a clear understanding of your audience, you can begin to craft your purpose statement with their needs and interests in mind. This will help ensure that your statement is effective in communicating your goals and objectives to your readers.

For example, if you’re writing a purpose statement for a research paper on the effects of climate change on agriculture, your audience may be fellow researchers in the field of environmental science. In this case, you would want to make sure that your purpose statement is written in a way that is clear and concise, using technical language that is familiar to your audience.

Or, if you’re writing a purpose statement for a business proposal to potential investors, your audience may be less familiar with the technical aspects of your project. In this case, you would want to make sure that your purpose statement is written in a way that is easy to understand, using clear and concise language that highlights the benefits of your proposal.

The key to defining your audience is to put yourself in their shoes and consider what they need and want from your purpose statement.

Part 5 Section 3: Outlining Your Methods

After you have identified the purpose of your statement, it is time to outline your methods. This section should describe how you plan to achieve your goal and the steps you will take to get there. Here are a few tips to help you outline your methods effectively:

• Start with a general overview: Begin by providing a brief overview of the methods you plan to use. This will give your readers a sense of what to expect in the following paragraphs.
• Break down your methods: Break your methods down into smaller, more manageable steps. This will make it easier for you to stay organized and for your readers to follow along.
• Use bullet points: Bullet points can help you organize your ideas and make your methods easier to read. Use them to list the steps you will take to achieve your goal.
• Be specific: Make sure you are specific about the methods you plan to use. This will help your readers understand exactly what you are doing and why.
• Provide examples: Use examples to illustrate your methods. This will make it easier for your readers to understand what you are trying to accomplish.

Part 6 Section 4: Stating the Expected Outcomes

After defining the problem and the purpose of your research, it’s time to state the expected outcomes. This is where you describe what you hope to achieve by conducting your research. The expected outcomes should be specific and measurable, so you can determine if you have achieved your goals.

It’s important to be realistic when stating your expected outcomes. Don’t make exaggerated or false claims, and don’t promise something that you can’t deliver. Your expected outcomes should be based on your research question and the purpose of your study.

Here are some examples of expected outcomes:

• To identify the factors that contribute to employee turnover in the company.
• To develop a new marketing strategy that will increase sales by 20% within the next year.
• To evaluate the effectiveness of a new training program for improving customer service.
• To determine the impact of social media on consumer behavior.

When stating your expected outcomes, make sure they align with your research question and purpose statement. This will help you stay focused on your goals and ensure that your research is relevant and meaningful.

In addition to stating your expected outcomes, you should also describe how you will measure them. This could involve collecting data through surveys, interviews, or experiments, or analyzing existing data from sources such as government reports or industry publications.

Part 7 Purpose Statement Example for a Research Paper

If you are writing a research paper, your purpose statement should clearly state the objective of your study. Here is an example of a purpose statement for a research paper:

The purpose of this study is to investigate the effects of social media on the mental health of teenagers in the United States.

This purpose statement clearly states the objective of the study and provides a specific focus for the research.

Part 8 Purpose Statement Example For Personal Goals

When writing a purpose statement for your personal goals, it’s important to clearly define what you want to achieve and why. Here’s a template that can help you get started:

“I want to [goal] so that [reason]. I will achieve this by [action].”

Example: “I want to lose 10 pounds so that I can feel more confident in my body. I will achieve this by going to the gym three times a week and cutting out sugary snacks.”

Remember to be specific and realistic when setting your goals and actions, and to regularly review and adjust your purpose statement as needed.

Research Purpose, Hypotheses, and Questions

Four key components to a research project are the purpose statement, research questions, hypotheses, and research objectives. In this post, we will define each of these.

Definitions

The purpose of this study is to examine the relationship between college completion and organizational commitment of undergraduate students in Thailand. 

Here is an example of a qualitative purpose statement.

The purpose of this study is to explore student experiences at a university in Thailand about completing their tertiary degree.

Both of these examples are short one-sentence responses to what the study will attempt to do. This is a critical first step in shaping the study.

Research Question

The research question(s) in a quantitative or qualitative study narrows the purpose down to a specific question(s) for the researcher to find answers. Below are examples from both the quantitative and qualitative perspective. We are continuing the research themes from the previous section on the purpose statement.

Quantitative

Does organizational commitment affect college completion of students?

Qualitative

What kinds of experiences have students had while completing their degree?

On closer examination, you may have noticed that the research questions sound a lot like the purpose statement. Research questions often split a part a long complex purpose statement into several questions. This is why questions sound so redundant when compared to the purpose statement. Despite this apparent problem, this thought process helps researchers to organize their thinking and proceed in a manner that is much more efficient.

The next two components only relate to quantitative research and they are the hypotheses and research objective(s). For this reason our illustration of qualitative concepts will stop at this point.

Hypotheses are statements a researcher makes about the potential outcome(s) of a study based on the examination of literature. Below is an example from the same theme as before.

Students who have a higher perception of organizational commitment will also have a higher likelihood of completing college.

Again, the wording of the research questions, hypotheses and purpose statement are similarly. The difference is only slightly and is due to context. Seeing these similarities quickly will help you to move faster in finishing a study. The difference between these elements is a matter of perspective rather than a strong difference, as they do sound awfully similar.

Research Objectives

Research objectives are the goals a researcher has for a study. This component is not always included in a study. Below is an example.

To examine the correlation between organizational commitment and the rate of college completion

10 thoughts on “ research purpose, hypotheses, and questions ”.

This is the wrong use of the word, it should be “their” not “there”.

The purpose of this study is to explore student experiences at a university in Thailand about completing there tertiary degree.

Whoops, thanks for catching that

Thank you for this, very helpful 🙂

Glad to be of service

As an emerging researcher, my worry is that I have six objectives but five research questions and hypotheses. Am I correct or they must all be the same in times of numbers? Thank you

Thank you, this information helped me so much.

The development of research questions and the subsequent hypotheses are prerequisites to defining the main research purpose and specific objectives of a study. Consequently, these objectives determine the study design and research outcome. The development of research questions is a process based on knowledge of current trends, cutting-edge studies, and technological advances in the research field. Excellent research questions are focused and require a comprehensive literature search and in-depth understanding of the problem being investigated. Initially, research questions may be written as descriptive questions which could be developed into inferential questions. These questions must be specific and concise to provide a clear foundation for developing hypotheses. Hypotheses are more formal predictions about the research outcomes. These specify the possible results that may or may not be expected regarding the relationship between groups. Thus, research questions and hypotheses clarify the main purpose and specific objectives of the study, which in turn dictate the design of the study, its direction, and outcome. Studies developed from good research questions and hypotheses will have trustworthy outcomes with wide-ranging social and health implications.

INTRODUCTION

Scientific research is usually initiated by posing evidenced-based research questions which are then explicitly restated as hypotheses. 1 , 2 The hypotheses provide directions to guide the study, solutions, explanations, and expected results. 3 , 4 Both research questions and hypotheses are essentially formulated based on conventional theories and real-world processes, which allow the inception of novel studies and the ethical testing of ideas. 5 , 6

It is crucial to have knowledge of both quantitative and qualitative research 2 as both types of research involve writing research questions and hypotheses. 7 However, these crucial elements of research are sometimes overlooked; if not overlooked, then framed without the forethought and meticulous attention it needs. Planning and careful consideration are needed when developing quantitative or qualitative research, particularly when conceptualizing research questions and hypotheses. 4

There is a continuing need to support researchers in the creation of innovative research questions and hypotheses, as well as for journal articles that carefully review these elements. 1 When research questions and hypotheses are not carefully thought of, unethical studies and poor outcomes usually ensue. Carefully formulated research questions and hypotheses define well-founded objectives, which in turn determine the appropriate design, course, and outcome of the study. This article then aims to discuss in detail the various aspects of crafting research questions and hypotheses, with the goal of guiding researchers as they develop their own. Examples from the authors and peer-reviewed scientific articles in the healthcare field are provided to illustrate key points.

DEFINITIONS AND RELATIONSHIP OF RESEARCH QUESTIONS AND HYPOTHESES

A research question is what a study aims to answer after data analysis and interpretation. The answer is written in length in the discussion section of the paper. Thus, the research question gives a preview of the different parts and variables of the study meant to address the problem posed in the research question. 1 An excellent research question clarifies the research writing while facilitating understanding of the research topic, objective, scope, and limitations of the study. 5

On the other hand, a research hypothesis is an educated statement of an expected outcome. This statement is based on background research and current knowledge. 8 , 9 The research hypothesis makes a specific prediction about a new phenomenon 10 or a formal statement on the expected relationship between an independent variable and a dependent variable. 3 , 11 It provides a tentative answer to the research question to be tested or explored. 4

Hypotheses employ reasoning to predict a theory-based outcome. 10 These can also be developed from theories by focusing on components of theories that have not yet been observed. 10 The validity of hypotheses is often based on the testability of the prediction made in a reproducible experiment. 8

Conversely, hypotheses can also be rephrased as research questions. Several hypotheses based on existing theories and knowledge may be needed to answer a research question. Developing ethical research questions and hypotheses creates a research design that has logical relationships among variables. These relationships serve as a solid foundation for the conduct of the study. 4 , 11 Haphazardly constructed research questions can result in poorly formulated hypotheses and improper study designs, leading to unreliable results. Thus, the formulations of relevant research questions and verifiable hypotheses are crucial when beginning research. 12

CHARACTERISTICS OF GOOD RESEARCH QUESTIONS AND HYPOTHESES

Excellent research questions are specific and focused. These integrate collective data and observations to confirm or refute the subsequent hypotheses. Well-constructed hypotheses are based on previous reports and verify the research context. These are realistic, in-depth, sufficiently complex, and reproducible. More importantly, these hypotheses can be addressed and tested. 13

There are several characteristics of well-developed hypotheses. Good hypotheses are 1) empirically testable 7 , 10 , 11 , 13 ; 2) backed by preliminary evidence 9 ; 3) testable by ethical research 7 , 9 ; 4) based on original ideas 9 ; 5) have evidenced-based logical reasoning 10 ; and 6) can be predicted. 11 Good hypotheses can infer ethical and positive implications, indicating the presence of a relationship or effect relevant to the research theme. 7 , 11 These are initially developed from a general theory and branch into specific hypotheses by deductive reasoning. In the absence of a theory to base the hypotheses, inductive reasoning based on specific observations or findings form more general hypotheses. 10

TYPES OF RESEARCH QUESTIONS AND HYPOTHESES

Research questions and hypotheses are developed according to the type of research, which can be broadly classified into quantitative and qualitative research. We provide a summary of the types of research questions and hypotheses under quantitative and qualitative research categories in Table 1 .

Research questions in quantitative research

In quantitative research, research questions inquire about the relationships among variables being investigated and are usually framed at the start of the study. These are precise and typically linked to the subject population, dependent and independent variables, and research design. 1 Research questions may also attempt to describe the behavior of a population in relation to one or more variables, or describe the characteristics of variables to be measured ( descriptive research questions ). 1 , 5 , 14 These questions may also aim to discover differences between groups within the context of an outcome variable ( comparative research questions ), 1 , 5 , 14 or elucidate trends and interactions among variables ( relationship research questions ). 1 , 5 We provide examples of descriptive, comparative, and relationship research questions in quantitative research in Table 2 .

Hypotheses in quantitative research

In quantitative research, hypotheses predict the expected relationships among variables. 15 Relationships among variables that can be predicted include 1) between a single dependent variable and a single independent variable ( simple hypothesis ) or 2) between two or more independent and dependent variables ( complex hypothesis ). 4 , 11 Hypotheses may also specify the expected direction to be followed and imply an intellectual commitment to a particular outcome ( directional hypothesis ) 4 . On the other hand, hypotheses may not predict the exact direction and are used in the absence of a theory, or when findings contradict previous studies ( non-directional hypothesis ). 4 In addition, hypotheses can 1) define interdependency between variables ( associative hypothesis ), 4 2) propose an effect on the dependent variable from manipulation of the independent variable ( causal hypothesis ), 4 3) state a negative relationship between two variables ( null hypothesis ), 4 , 11 , 15 4) replace the working hypothesis if rejected ( alternative hypothesis ), 15 explain the relationship of phenomena to possibly generate a theory ( working hypothesis ), 11 5) involve quantifiable variables that can be tested statistically ( statistical hypothesis ), 11 6) or express a relationship whose interlinks can be verified logically ( logical hypothesis ). 11 We provide examples of simple, complex, directional, non-directional, associative, causal, null, alternative, working, statistical, and logical hypotheses in quantitative research, as well as the definition of quantitative hypothesis-testing research in Table 3 .

Research questions in qualitative research

Unlike research questions in quantitative research, research questions in qualitative research are usually continuously reviewed and reformulated. The central question and associated subquestions are stated more than the hypotheses. 15 The central question broadly explores a complex set of factors surrounding the central phenomenon, aiming to present the varied perspectives of participants. 15

There are varied goals for which qualitative research questions are developed. These questions can function in several ways, such as to 1) identify and describe existing conditions ( contextual research question s); 2) describe a phenomenon ( descriptive research questions ); 3) assess the effectiveness of existing methods, protocols, theories, or procedures ( evaluation research questions ); 4) examine a phenomenon or analyze the reasons or relationships between subjects or phenomena ( explanatory research questions ); or 5) focus on unknown aspects of a particular topic ( exploratory research questions ). 5 In addition, some qualitative research questions provide new ideas for the development of theories and actions ( generative research questions ) or advance specific ideologies of a position ( ideological research questions ). 1 Other qualitative research questions may build on a body of existing literature and become working guidelines ( ethnographic research questions ). Research questions may also be broadly stated without specific reference to the existing literature or a typology of questions ( phenomenological research questions ), may be directed towards generating a theory of some process ( grounded theory questions ), or may address a description of the case and the emerging themes ( qualitative case study questions ). 15 We provide examples of contextual, descriptive, evaluation, explanatory, exploratory, generative, ideological, ethnographic, phenomenological, grounded theory, and qualitative case study research questions in qualitative research in Table 4 , and the definition of qualitative hypothesis-generating research in Table 5 .

Qualitative studies usually pose at least one central research question and several subquestions starting with How or What . These research questions use exploratory verbs such as explore or describe . These also focus on one central phenomenon of interest, and may mention the participants and research site. 15

Hypotheses in qualitative research

Hypotheses in qualitative research are stated in the form of a clear statement concerning the problem to be investigated. Unlike in quantitative research where hypotheses are usually developed to be tested, qualitative research can lead to both hypothesis-testing and hypothesis-generating outcomes. 2 When studies require both quantitative and qualitative research questions, this suggests an integrative process between both research methods wherein a single mixed-methods research question can be developed. 1

FRAMEWORKS FOR DEVELOPING RESEARCH QUESTIONS AND HYPOTHESES

Research questions followed by hypotheses should be developed before the start of the study. 1 , 12 , 14 It is crucial to develop feasible research questions on a topic that is interesting to both the researcher and the scientific community. This can be achieved by a meticulous review of previous and current studies to establish a novel topic. Specific areas are subsequently focused on to generate ethical research questions. The relevance of the research questions is evaluated in terms of clarity of the resulting data, specificity of the methodology, objectivity of the outcome, depth of the research, and impact of the study. 1 , 5 These aspects constitute the FINER criteria (i.e., Feasible, Interesting, Novel, Ethical, and Relevant). 1 Clarity and effectiveness are achieved if research questions meet the FINER criteria. In addition to the FINER criteria, Ratan et al. described focus, complexity, novelty, feasibility, and measurability for evaluating the effectiveness of research questions. 14

The PICOT and PEO frameworks are also used when developing research questions. 1 The following elements are addressed in these frameworks, PICOT: P-population/patients/problem, I-intervention or indicator being studied, C-comparison group, O-outcome of interest, and T-timeframe of the study; PEO: P-population being studied, E-exposure to preexisting conditions, and O-outcome of interest. 1 Research questions are also considered good if these meet the “FINERMAPS” framework: Feasible, Interesting, Novel, Ethical, Relevant, Manageable, Appropriate, Potential value/publishable, and Systematic. 14

As we indicated earlier, research questions and hypotheses that are not carefully formulated result in unethical studies or poor outcomes. To illustrate this, we provide some examples of ambiguous research question and hypotheses that result in unclear and weak research objectives in quantitative research ( Table 6 ) 16 and qualitative research ( Table 7 ) 17 , and how to transform these ambiguous research question(s) and hypothesis(es) into clear and good statements.

CONSTRUCTING RESEARCH QUESTIONS AND HYPOTHESES

To construct effective research questions and hypotheses, it is very important to 1) clarify the background and 2) identify the research problem at the outset of the research, within a specific timeframe. 9 Then, 3) review or conduct preliminary research to collect all available knowledge about the possible research questions by studying theories and previous studies. 18 Afterwards, 4) construct research questions to investigate the research problem. Identify variables to be accessed from the research questions 4 and make operational definitions of constructs from the research problem and questions. Thereafter, 5) construct specific deductive or inductive predictions in the form of hypotheses. 4 Finally, 6) state the study aims . This general flow for constructing effective research questions and hypotheses prior to conducting research is shown in Fig. 1 .

Research questions are used more frequently in qualitative research than objectives or hypotheses. 3 These questions seek to discover, understand, explore or describe experiences by asking “What” or “How.” The questions are open-ended to elicit a description rather than to relate variables or compare groups. The questions are continually reviewed, reformulated, and changed during the qualitative study. 3 Research questions are also used more frequently in survey projects than hypotheses in experiments in quantitative research to compare variables and their relationships.

Hypotheses are constructed based on the variables identified and as an if-then statement, following the template, ‘If a specific action is taken, then a certain outcome is expected.’ At this stage, some ideas regarding expectations from the research to be conducted must be drawn. 18 Then, the variables to be manipulated (independent) and influenced (dependent) are defined. 4 Thereafter, the hypothesis is stated and refined, and reproducible data tailored to the hypothesis are identified, collected, and analyzed. 4 The hypotheses must be testable and specific, 18 and should describe the variables and their relationships, the specific group being studied, and the predicted research outcome. 18 Hypotheses construction involves a testable proposition to be deduced from theory, and independent and dependent variables to be separated and measured separately. 3 Therefore, good hypotheses must be based on good research questions constructed at the start of a study or trial. 12

In summary, research questions are constructed after establishing the background of the study. Hypotheses are then developed based on the research questions. Thus, it is crucial to have excellent research questions to generate superior hypotheses. In turn, these would determine the research objectives and the design of the study, and ultimately, the outcome of the research. 12 Algorithms for building research questions and hypotheses are shown in Fig. 2 for quantitative research and in Fig. 3 for qualitative research.

EXAMPLES OF RESEARCH QUESTIONS FROM PUBLISHED ARTICLES

• EXAMPLE 1. Descriptive research question (quantitative research)
• - Presents research variables to be assessed (distinct phenotypes and subphenotypes)
• “BACKGROUND: Since COVID-19 was identified, its clinical and biological heterogeneity has been recognized. Identifying COVID-19 phenotypes might help guide basic, clinical, and translational research efforts.
• RESEARCH QUESTION: Does the clinical spectrum of patients with COVID-19 contain distinct phenotypes and subphenotypes? ” 19
• EXAMPLE 2. Relationship research question (quantitative research)
• - Shows interactions between dependent variable (static postural control) and independent variable (peripheral visual field loss)
• “Background: Integration of visual, vestibular, and proprioceptive sensations contributes to postural control. People with peripheral visual field loss have serious postural instability. However, the directional specificity of postural stability and sensory reweighting caused by gradual peripheral visual field loss remain unclear.
• Research question: What are the effects of peripheral visual field loss on static postural control ?” 20
• EXAMPLE 3. Comparative research question (quantitative research)
• - Clarifies the difference among groups with an outcome variable (patients enrolled in COMPERA with moderate PH or severe PH in COPD) and another group without the outcome variable (patients with idiopathic pulmonary arterial hypertension (IPAH))
• “BACKGROUND: Pulmonary hypertension (PH) in COPD is a poorly investigated clinical condition.
• RESEARCH QUESTION: Which factors determine the outcome of PH in COPD?
• STUDY DESIGN AND METHODS: We analyzed the characteristics and outcome of patients enrolled in the Comparative, Prospective Registry of Newly Initiated Therapies for Pulmonary Hypertension (COMPERA) with moderate or severe PH in COPD as defined during the 6th PH World Symposium who received medical therapy for PH and compared them with patients with idiopathic pulmonary arterial hypertension (IPAH) .” 21
• EXAMPLE 4. Exploratory research question (qualitative research)
• - Explores areas that have not been fully investigated (perspectives of families and children who receive care in clinic-based child obesity treatment) to have a deeper understanding of the research problem
• “Problem: Interventions for children with obesity lead to only modest improvements in BMI and long-term outcomes, and data are limited on the perspectives of families of children with obesity in clinic-based treatment. This scoping review seeks to answer the question: What is known about the perspectives of families and children who receive care in clinic-based child obesity treatment? This review aims to explore the scope of perspectives reported by families of children with obesity who have received individualized outpatient clinic-based obesity treatment.” 22
• EXAMPLE 5. Relationship research question (quantitative research)
• - Defines interactions between dependent variable (use of ankle strategies) and independent variable (changes in muscle tone)
• “Background: To maintain an upright standing posture against external disturbances, the human body mainly employs two types of postural control strategies: “ankle strategy” and “hip strategy.” While it has been reported that the magnitude of the disturbance alters the use of postural control strategies, it has not been elucidated how the level of muscle tone, one of the crucial parameters of bodily function, determines the use of each strategy. We have previously confirmed using forward dynamics simulations of human musculoskeletal models that an increased muscle tone promotes the use of ankle strategies. The objective of the present study was to experimentally evaluate a hypothesis: an increased muscle tone promotes the use of ankle strategies. Research question: Do changes in the muscle tone affect the use of ankle strategies ?” 23

EXAMPLES OF HYPOTHESES IN PUBLISHED ARTICLES

• EXAMPLE 1. Working hypothesis (quantitative research)
• - A hypothesis that is initially accepted for further research to produce a feasible theory
• “As fever may have benefit in shortening the duration of viral illness, it is plausible to hypothesize that the antipyretic efficacy of ibuprofen may be hindering the benefits of a fever response when taken during the early stages of COVID-19 illness .” 24
• “In conclusion, it is plausible to hypothesize that the antipyretic efficacy of ibuprofen may be hindering the benefits of a fever response . The difference in perceived safety of these agents in COVID-19 illness could be related to the more potent efficacy to reduce fever with ibuprofen compared to acetaminophen. Compelling data on the benefit of fever warrant further research and review to determine when to treat or withhold ibuprofen for early stage fever for COVID-19 and other related viral illnesses .” 24
• EXAMPLE 2. Exploratory hypothesis (qualitative research)
• - Explores particular areas deeper to clarify subjective experience and develop a formal hypothesis potentially testable in a future quantitative approach
• “We hypothesized that when thinking about a past experience of help-seeking, a self distancing prompt would cause increased help-seeking intentions and more favorable help-seeking outcome expectations .” 25
• “Conclusion
• Although a priori hypotheses were not supported, further research is warranted as results indicate the potential for using self-distancing approaches to increasing help-seeking among some people with depressive symptomatology.” 25
• EXAMPLE 3. Hypothesis-generating research to establish a framework for hypothesis testing (qualitative research)
• “We hypothesize that compassionate care is beneficial for patients (better outcomes), healthcare systems and payers (lower costs), and healthcare providers (lower burnout). ” 26
• Compassionomics is the branch of knowledge and scientific study of the effects of compassionate healthcare. Our main hypotheses are that compassionate healthcare is beneficial for (1) patients, by improving clinical outcomes, (2) healthcare systems and payers, by supporting financial sustainability, and (3) HCPs, by lowering burnout and promoting resilience and well-being. The purpose of this paper is to establish a scientific framework for testing the hypotheses above . If these hypotheses are confirmed through rigorous research, compassionomics will belong in the science of evidence-based medicine, with major implications for all healthcare domains.” 26
• EXAMPLE 4. Statistical hypothesis (quantitative research)
• - An assumption is made about the relationship among several population characteristics ( gender differences in sociodemographic and clinical characteristics of adults with ADHD ). Validity is tested by statistical experiment or analysis ( chi-square test, Students t-test, and logistic regression analysis)
• “Our research investigated gender differences in sociodemographic and clinical characteristics of adults with ADHD in a Japanese clinical sample. Due to unique Japanese cultural ideals and expectations of women's behavior that are in opposition to ADHD symptoms, we hypothesized that women with ADHD experience more difficulties and present more dysfunctions than men . We tested the following hypotheses: first, women with ADHD have more comorbidities than men with ADHD; second, women with ADHD experience more social hardships than men, such as having less full-time employment and being more likely to be divorced.” 27
• “Statistical Analysis
• ( text omitted ) Between-gender comparisons were made using the chi-squared test for categorical variables and Students t-test for continuous variables…( text omitted ). A logistic regression analysis was performed for employment status, marital status, and comorbidity to evaluate the independent effects of gender on these dependent variables.” 27

EXAMPLES OF HYPOTHESIS AS WRITTEN IN PUBLISHED ARTICLES IN RELATION TO OTHER PARTS

• EXAMPLE 1. Background, hypotheses, and aims are provided
• “Pregnant women need skilled care during pregnancy and childbirth, but that skilled care is often delayed in some countries …( text omitted ). The focused antenatal care (FANC) model of WHO recommends that nurses provide information or counseling to all pregnant women …( text omitted ). Job aids are visual support materials that provide the right kind of information using graphics and words in a simple and yet effective manner. When nurses are not highly trained or have many work details to attend to, these job aids can serve as a content reminder for the nurses and can be used for educating their patients (Jennings, Yebadokpo, Affo, & Agbogbe, 2010) ( text omitted ). Importantly, additional evidence is needed to confirm how job aids can further improve the quality of ANC counseling by health workers in maternal care …( text omitted )” 28
• “ This has led us to hypothesize that the quality of ANC counseling would be better if supported by job aids. Consequently, a better quality of ANC counseling is expected to produce higher levels of awareness concerning the danger signs of pregnancy and a more favorable impression of the caring behavior of nurses .” 28
• “This study aimed to examine the differences in the responses of pregnant women to a job aid-supported intervention during ANC visit in terms of 1) their understanding of the danger signs of pregnancy and 2) their impression of the caring behaviors of nurses to pregnant women in rural Tanzania.” 28
• EXAMPLE 2. Background, hypotheses, and aims are provided
• “We conducted a two-arm randomized controlled trial (RCT) to evaluate and compare changes in salivary cortisol and oxytocin levels of first-time pregnant women between experimental and control groups. The women in the experimental group touched and held an infant for 30 min (experimental intervention protocol), whereas those in the control group watched a DVD movie of an infant (control intervention protocol). The primary outcome was salivary cortisol level and the secondary outcome was salivary oxytocin level.” 29
• “ We hypothesize that at 30 min after touching and holding an infant, the salivary cortisol level will significantly decrease and the salivary oxytocin level will increase in the experimental group compared with the control group .” 29
• EXAMPLE 3. Background, aim, and hypothesis are provided
• “In countries where the maternal mortality ratio remains high, antenatal education to increase Birth Preparedness and Complication Readiness (BPCR) is considered one of the top priorities [1]. BPCR includes birth plans during the antenatal period, such as the birthplace, birth attendant, transportation, health facility for complications, expenses, and birth materials, as well as family coordination to achieve such birth plans. In Tanzania, although increasing, only about half of all pregnant women attend an antenatal clinic more than four times [4]. Moreover, the information provided during antenatal care (ANC) is insufficient. In the resource-poor settings, antenatal group education is a potential approach because of the limited time for individual counseling at antenatal clinics.” 30
• “This study aimed to evaluate an antenatal group education program among pregnant women and their families with respect to birth-preparedness and maternal and infant outcomes in rural villages of Tanzania.” 30
• “ The study hypothesis was if Tanzanian pregnant women and their families received a family-oriented antenatal group education, they would (1) have a higher level of BPCR, (2) attend antenatal clinic four or more times, (3) give birth in a health facility, (4) have less complications of women at birth, and (5) have less complications and deaths of infants than those who did not receive the education .” 30

Research questions and hypotheses are crucial components to any type of research, whether quantitative or qualitative. These questions should be developed at the very beginning of the study. Excellent research questions lead to superior hypotheses, which, like a compass, set the direction of research, and can often determine the successful conduct of the study. Many research studies have floundered because the development of research questions and subsequent hypotheses was not given the thought and meticulous attention needed. The development of research questions and hypotheses is an iterative process based on extensive knowledge of the literature and insightful grasp of the knowledge gap. Focused, concise, and specific research questions provide a strong foundation for constructing hypotheses which serve as formal predictions about the research outcomes. Research questions and hypotheses are crucial elements of research that should not be overlooked. They should be carefully thought of and constructed when planning research. This avoids unethical studies and poor outcomes by defining well-founded objectives that determine the design, course, and outcome of the study.

Purpose statement overview.

The purpose statement succinctly explains (on no more than 1 page) the objectives of the research study. These objectives must directly address the problem and help close the stated gap. Expressed as a formula:

Good purpose statements:

• Flow from the problem statement and actually address the proposed problem
• Are concise and clear
• Answer the question ‘Why are you doing this research?’
• Match the methodology (similar to research questions)
• Have a ‘hook’ to get the reader’s attention
• Set the stage by clearly stating, “The purpose of this (qualitative or quantitative) study is to ...

In PhD studies, the purpose usually involves applying a theory to solve the problem. In other words, the purpose tells the reader what the goal of the study is, and what your study will accomplish, through which theoretical lens. The purpose statement also includes brief information about direction, scope, and where the data will come from.

A problem and gap in combination can lead to different research objectives, and hence, different purpose statements. In the example from above where the problem was severe underrepresentation of female CEOs in Fortune 500 companies and the identified gap related to lack of research of male-dominated boards; one purpose might be to explore implicit biases in male-dominated boards through the lens of feminist theory. Another purpose may be to determine how board members rated female and male candidates on scales of competency, professionalism, and experience to predict which candidate will be selected for the CEO position. The first purpose may involve a qualitative ethnographic study in which the researcher observes board meetings and hiring interviews; the second may involve a quantitative regression analysis. The outcomes will be very different, so it’s important that you find out exactly how you want to address a problem and help close a gap!

The purpose of the study must not only align with the problem and address a gap; it must also align with the chosen research method. In fact, the DP/DM template requires you to name the  research method at the very beginning of the purpose statement. The research verb must match the chosen method. In general, quantitative studies involve “closed-ended” research verbs such as determine , measure , correlate , explain , compare , validate , identify , or examine ; whereas qualitative studies involve “open-ended” research verbs such as explore , understand , narrate , articulate [meanings], discover , or develop .

A qualitative purpose statement following the color-coded problem statement (assumed here to be low well-being among financial sector employees) + gap (lack of research on followers of mid-level managers), might start like this:

In response to declining levels of employee well-being, the purpose of the qualitative phenomenology was to explore and understand the lived experiences related to the well-being of the followers of novice mid-level managers in the financial services industry. The levels of follower well-being have been shown to correlate to employee morale, turnover intention, and customer orientation (Eren et al., 2013). A combined framework of Leader-Member Exchange (LMX) Theory and the employee well-being concept informed the research questions and supported the inquiry, analysis, and interpretation of the experiences of followers of novice managers in the financial services industry.

A quantitative purpose statement for the same problem and gap might start like this:

In response to declining levels of employee well-being, the purpose of the quantitative correlational study was to determine which leadership factors predict employee well-being of the followers of novice mid-level managers in the financial services industry. Leadership factors were measured by the Leader-Member Exchange (LMX) assessment framework  by Mantlekow (2015), and employee well-being was conceptualized as a compound variable consisting of self-reported turnover-intent and psychological test scores from the Mental Health Survey (MHS) developed by Johns Hopkins University researchers.

Both of these purpose statements reflect viable research strategies and both align with the problem and gap so it’s up to the researcher to design a study in a manner that reflects personal preferences and desired study outcomes. Note that the quantitative research purpose incorporates operationalized concepts  or variables ; that reflect the way the researcher intends to measure the key concepts under study; whereas the qualitative purpose statement isn’t about translating the concepts under study as variables but instead aim to explore and understand the core research phenomenon.  

Best Practices for Writing your Purpose Statement

Always keep in mind that the dissertation process is iterative, and your writing, over time, will be refined as clarity is gradually achieved. Most of the time, greater clarity for the purpose statement and other components of the Dissertation is the result of a growing understanding of the literature in the field. As you increasingly master the literature you will also increasingly clarify the purpose of your study.

The purpose statement should flow directly from the problem statement. There should be clear and obvious alignment between the two and that alignment will get tighter and more pronounced as your work progresses.

The purpose statement should specifically address the reason for conducting the study, with emphasis on the word specifically. There should not be any doubt in your readers’ minds as to the purpose of your study. To achieve this level of clarity you will need to also insure there is no doubt in your mind as to the purpose of your study.

Many researchers benefit from stopping your work during the research process when insight strikes you and write about it while it is still fresh in your mind. This can help you clarify all aspects of a dissertation, including clarifying its purpose.

Your Chair and your committee members can help you to clarify your study’s purpose so carefully attend to any feedback they offer.

The purpose statement should reflect the research questions and vice versa. The chain of alignment that began with the research problem description and continues on to the research purpose, research questions, and methodology must be respected at all times during dissertation development. You are to succinctly describe the overarching goal of the study that reflects the research questions. Each research question narrows and focuses the purpose statement. Conversely, the purpose statement encompasses all of the research questions.

Identify in the purpose statement the research method as quantitative, qualitative or mixed (i.e., “The purpose of this [qualitative/quantitative/mixed] study is to ...)

Avoid the use of the phrase “research study” since the two words together are redundant.

Follow the initial declaration of purpose with a brief overview of how, with what instruments/data, with whom and where (as applicable) the study will be conducted. Identify variables/constructs and/or phenomenon/concept/idea. Since this section is to be a concise paragraph, emphasis must be placed on the word brief. However, adding these details will give your readers a very clear picture of the purpose of your research.

Developing the purpose section of your dissertation is usually not achieved in a single flash of insight. The process involves a great deal of reading to find out what other scholars have done to address the research topic and problem you have identified. The purpose section of your dissertation could well be the most important paragraph you write during your academic career, and every word should be carefully selected. Think of it as the DNA of your dissertation. Everything else you write should emerge directly and clearly from your purpose statement. In turn, your purpose statement should emerge directly and clearly from your research problem description. It is good practice to print out your problem statement and purpose statement and keep them in front of you as you work on each part of your dissertation in order to insure alignment.

It is helpful to collect several dissertations similar to the one you envision creating. Extract the problem descriptions and purpose statements of other dissertation authors and compare them in order to sharpen your thinking about your own work.  Comparing how other dissertation authors have handled the many challenges you are facing can be an invaluable exercise. Keep in mind that individual universities use their own tailored protocols for presenting key components of the dissertation so your review of these purpose statements should focus on content rather than form.

Once your purpose statement is set it must be consistently presented throughout the dissertation. This may require some recursive editing because the way you articulate your purpose may evolve as you work on various aspects of your dissertation. Whenever you make an adjustment to your purpose statement you should carefully follow up on the editing and conceptual ramifications throughout the entire document.

In establishing your purpose you should NOT advocate for a particular outcome. Research should be done to answer questions not prove a point. As a researcher, you are to inquire with an open mind, and even when you come to the work with clear assumptions, your job is to prove the validity of the conclusions reached. For example, you would not say the purpose of your research project is to demonstrate that there is a relationship between two variables. Such a statement presupposes you know the answer before your research is conducted and promotes or supports (advocates on behalf of) a particular outcome. A more appropriate purpose statement would be to examine or explore the relationship between two variables.

Your purpose statement should not imply that you are going to prove something. You may be surprised to learn that we cannot prove anything in scholarly research for two reasons. First, in quantitative analyses, statistical tests calculate the probability that something is true rather than establishing it as true. Second, in qualitative research, the study can only purport to describe what is occurring from the perspective of the participants. Whether or not the phenomenon they are describing is true in a larger context is not knowable. We cannot observe the phenomenon in all settings and in all circumstances.

Writing your Purpose Statement

It is important to distinguish in your mind the differences between the Problem Statement and Purpose Statement.

The Problem Statement is why I am doing the research

The Purpose Statement is what type of research I am doing to fit or address the problem

The Purpose Statement includes:

• Method of Study
• Specific Population

Remember, as you are contemplating what to include in your purpose statement and then when you are writing it, the purpose statement is a concise paragraph that describes the intent of the study, and it should flow directly from the problem statement.  It should specifically address the reason for conducting the study, and reflect the research questions.  Further, it should identify the research method as qualitative, quantitative, or mixed.  Then provide a brief overview of how the study will be conducted, with what instruments/data collection methods, and with whom (subjects) and where (as applicable). Finally, you should identify variables/constructs and/or phenomenon/concept/idea.

Qualitative Purpose Statement

Creswell (2002) suggested for writing purpose statements in qualitative research include using deliberate phrasing to alert the reader to the purpose statement. Verbs that indicate what will take place in the research and the use of non-directional language that do not suggest an outcome are key. A purpose statement should focus on a single idea or concept, with a broad definition of the idea or concept. How the concept was investigated should also be included, as well as participants in the study and locations for the research to give the reader a sense of with whom and where the study took place. 

Creswell (2003) advised the following script for purpose statements in qualitative research:

“The purpose of this qualitative_________________ (strategy of inquiry, such as ethnography, case study, or other type) study is (was? will be?) to ________________ (understand? describe? develop? discover?) the _________________(central phenomenon being studied) for ______________ (the participants, such as the individual, groups, organization) at __________(research site). At this stage in the research, the __________ (central phenomenon being studied) will be generally defined as ___________________ (provide a general definition)” (pg. 90).

Quantitative Purpose Statement

Creswell (2003) offers vast differences between the purpose statements written for qualitative research and those written for quantitative research, particularly with respect to language and the inclusion of variables. The comparison of variables is often a focus of quantitative research, with the variables distinguishable by either the temporal order or how they are measured. As with qualitative research purpose statements, Creswell (2003) recommends the use of deliberate language to alert the reader to the purpose of the study, but quantitative purpose statements also include the theory or conceptual framework guiding the study and the variables that are being studied and how they are related. 

Creswell (2003) suggests the following script for drafting purpose statements in quantitative research:

“The purpose of this _____________________ (experiment? survey?) study is (was? will be?) to test the theory of _________________that _________________ (compares? relates?) the ___________(independent variable) to _________________________(dependent variable), controlling for _______________________ (control variables) for ___________________ (participants) at _________________________ (the research site). The independent variable(s) _____________________ will be generally defined as _______________________ (provide a general definition). The dependent variable(s) will be generally defined as _____________________ (provide a general definition), and the control and intervening variables(s), _________________ (identify the control and intervening variables) will be statistically controlled in this study” (pg. 97).

Sample Purpose Statements

• The purpose of this qualitative study was to determine how participation in service-learning in an alternative school impacted students academically, civically, and personally.  There is ample evidence demonstrating the failure of schools for students at-risk; however, there is still a need to demonstrate why these students are successful in non-traditional educational programs like the service-learning model used at TDS.  This study was unique in that it examined one alternative school’s approach to service-learning in a setting where students not only serve, but faculty serve as volunteer teachers.  The use of a constructivist approach in service-learning in an alternative school setting was examined in an effort to determine whether service-learning participation contributes positively to academic, personal, and civic gain for students, and to examine student and teacher views regarding the overall outcomes of service-learning.  This study was completed using an ethnographic approach that included observations, content analysis, and interviews with teachers at The David School.
• The purpose of this quantitative non-experimental cross-sectional linear multiple regression design was to investigate the relationship among early childhood teachers’ self-reported assessment of multicultural awareness as measured by responses from the Teacher Multicultural Attitude Survey (TMAS) and supervisors’ observed assessment of teachers’ multicultural competency skills as measured by the Multicultural Teaching Competency Scale (MTCS) survey. Demographic data such as number of multicultural training hours, years teaching in Dubai, curriculum program at current school, and age were also examined and their relationship to multicultural teaching competency. The study took place in the emirate of Dubai where there were 14,333 expatriate teachers employed in private schools (KHDA, 2013b).
• The purpose of this quantitative, non-experimental study is to examine the degree to which stages of change, gender, acculturation level and trauma types predicts the reluctance of Arab refugees, aged 18 and over, in the Dearborn, MI area, to seek professional help for their mental health needs. This study will utilize four instruments to measure these variables: University of Rhode Island Change Assessment (URICA: DiClemente & Hughes, 1990); Cumulative Trauma Scale (Kira, 2012); Acculturation Rating Scale for Arabic Americans-II Arabic and English (ARSAA-IIA, ARSAA-IIE: Jadalla & Lee, 2013), and a demographic survey. This study will examine 1) the relationship between stages of change, gender, acculturation levels, and trauma types and Arab refugees’ help-seeking behavior, 2) the degree to which any of these variables can predict Arab refugee help-seeking behavior.  Additionally, the outcome of this study could provide researchers and clinicians with a stage-based model, TTM, for measuring Arab refugees’ help-seeking behavior and lay a foundation for how TTM can help target the clinical needs of Arab refugees. Lastly, this attempt to apply the TTM model to Arab refugees’ condition could lay the foundation for future research to investigate the application of TTM to clinical work among refugee populations.
• The purpose of this qualitative, phenomenological study is to describe the lived experiences of LLM for 10 EFL learners in rural Guatemala and to utilize that data to determine how it conforms to, or possibly challenges, current theoretical conceptions of LLM. In accordance with Morse’s (1994) suggestion that a phenomenological study should utilize at least six participants, this study utilized semi-structured interviews with 10 EFL learners to explore why and how they have experienced the motivation to learn English throughout their lives. The methodology of horizontalization was used to break the interview protocols into individual units of meaning before analyzing these units to extract the overarching themes (Moustakas, 1994). These themes were then interpreted into a detailed description of LLM as experienced by EFL students in this context. Finally, the resulting description was analyzed to discover how these learners’ lived experiences with LLM conformed with and/or diverged from current theories of LLM.
• The purpose of this qualitative, embedded, multiple case study was to examine how both parent-child attachment relationships are impacted by the quality of the paternal and maternal caregiver-child interactions that occur throughout a maternal deployment, within the context of dual-military couples. In order to examine this phenomenon, an embedded, multiple case study was conducted, utilizing an attachment systems metatheory perspective. The study included four dual-military couples who experienced a maternal deployment to Operation Iraqi Freedom (OIF) or Operation Enduring Freedom (OEF) when they had at least one child between 8 weeks-old to 5 years-old.  Each member of the couple participated in an individual, semi-structured interview with the researcher and completed the Parenting Relationship Questionnaire (PRQ). “The PRQ is designed to capture a parent’s perspective on the parent-child relationship” (Pearson, 2012, para. 1) and was used within the proposed study for this purpose. The PRQ was utilized to triangulate the data (Bekhet & Zauszniewski, 2012) as well as to provide some additional information on the parents’ perspective of the quality of the parent-child attachment relationship in regards to communication, discipline, parenting confidence, relationship satisfaction, and time spent together (Pearson, 2012). The researcher utilized the semi-structured interview to collect information regarding the parents' perspectives of the quality of their parental caregiver behaviors during the deployment cycle, the mother's parent-child interactions while deployed, the behavior of the child or children at time of reunification, and the strategies or behaviors the parents believe may have contributed to their child's behavior at the time of reunification. The results of this study may be utilized by the military, and by civilian providers, to develop proactive and preventive measures that both providers and parents can implement, to address any potential adverse effects on the parent-child attachment relationship, identified through the proposed study. The results of this study may also be utilized to further refine and understand the integration of attachment theory and systems theory, in both clinical and research settings, within the field of marriage and family therapy.
