How to Justify Your Methods in a Thesis or Dissertation

4-minute read

• 1st May 2023

Writing a thesis or dissertation is hard work. You’ve devoted countless hours to your research, and you want your results to be taken seriously. But how does your professor or evaluating committee know that they can trust your results? You convince them by justifying your research methods.

What Does Justifying Your Methods Mean?

In simple terms, your methods are the tools you use to obtain your data, and the justification (which is also called the methodology ) is the analysis of those tools. In your justification, your goal is to demonstrate that your research is both rigorously conducted and replicable so your audience recognizes that your results are legitimate.

The formatting and structure of your justification will depend on your field of study and your institution’s requirements, but below, we’ve provided questions to ask yourself as you outline your justification.

Why Did You Choose Your Method of Gathering Data?

Does your study rely on quantitative data, qualitative data, or both? Certain types of data work better for certain studies. How did you choose to gather that data? Evaluate your approach to collecting data in light of your research question. Did you consider any alternative approaches? If so, why did you decide not to use them? Highlight the pros and cons of various possible methods if necessary. Research results aren’t valid unless the data are valid, so you have to convince your reader that they are.

How Did You Evaluate Your Data?

Collecting your data was only the first part of your study. Once you had them, how did you use them? Do your results involve cross-referencing? If so, how was this accomplished? Which statistical analyses did you run, and why did you choose them? Are they common in your field? How did you make sure your data were statistically significant ? Is your effect size small, medium, or large? Numbers don’t always lend themselves to an obvious outcome. Here, you want to provide a clear link between the Methods and Results sections of your paper.

Did You Use Any Unconventional Approaches in Your Study?

Most fields have standard approaches to the research they use, but these approaches don’t work for every project. Did you use methods that other fields normally use, or did you need to come up with a different way of obtaining your data? Your reader will look at unconventional approaches with a more critical eye. Acknowledge the limitations of your method, but explain why the strengths of the method outweigh those limitations.

What Relevant Sources Can You Cite?

You can strengthen your justification by referencing existing research in your field. Citing these references can demonstrate that you’ve followed established practices for your type of research. Or you can discuss how you decided on your approach by evaluating other studies. Highlight the use of established techniques, tools, and measurements in your study. If you used an unconventional approach, justify it by providing evidence of a gap in the existing literature.

Two Final Tips:

●  When you’re writing your justification, write for your audience. Your purpose here is to provide more than a technical list of details and procedures. This section should focus more on the why and less on the how .

●  Consider your methodology as you’re conducting your research. Take thorough notes as you work to make sure you capture all the necessary details correctly. Eliminating any possible confusion or ambiguity will go a long way toward helping your justification.

In Conclusion:

Your goal in writing your justification is to explain not only the decisions you made but also the reasoning behind those decisions. It should be overwhelmingly clear to your audience that your study used the best possible methods to answer your research question. Properly justifying your methods will let your audience know that your research was effective and its results are valid.

How to Write the Rationale of the Study in Research (Examples)

What is the Rationale of the Study?

The rationale of the study is the justification for taking on a given study. It explains the reason the study was conducted or should be conducted. This means the study rationale should explain to the reader or examiner why the study is/was necessary. It is also sometimes called the “purpose” or “justification” of a study. While this is not difficult to grasp in itself, you might wonder how the rationale of the study is different from your research question or from the statement of the problem of your study, and how it fits into the rest of your thesis or research paper. 

The rationale of the study links the background of the study to your specific research question and justifies the need for the latter on the basis of the former. In brief, you first provide and discuss existing data on the topic, and then you tell the reader, based on the background evidence you just presented, where you identified gaps or issues and why you think it is important to address those. The problem statement, lastly, is the formulation of the specific research question you choose to investigate, following logically from your rationale, and the approach you are planning to use to do that.

Table of Contents:

How to write a rationale for a research paper , how do you justify the need for a research study.

• Study Rationale Example: Where Does It Go In Your Paper?

The basis for writing a research rationale is preliminary data or a clear description of an observation. If you are doing basic/theoretical research, then a literature review will help you identify gaps in current knowledge. In applied/practical research, you base your rationale on an existing issue with a certain process (e.g., vaccine proof registration) or practice (e.g., patient treatment) that is well documented and needs to be addressed. By presenting the reader with earlier evidence or observations, you can (and have to) convince them that you are not just repeating what other people have already done or said and that your ideas are not coming out of thin air. 

Once you have explained where you are coming from, you should justify the need for doing additional research–this is essentially the rationale of your study. Finally, when you have convinced the reader of the purpose of your work, you can end your introduction section with the statement of the problem of your research that contains clear aims and objectives and also briefly describes (and justifies) your methodological approach. 

When is the Rationale for Research Written?

The author can present the study rationale both before and after the research is conducted. 

• Before conducting research : The study rationale is a central component of the research proposal . It represents the plan of your work, constructed before the study is actually executed.
• Once research has been conducted : After the study is completed, the rationale is presented in a research article or  PhD dissertation  to explain why you focused on this specific research question. When writing the study rationale for this purpose, the author should link the rationale of the research to the aims and outcomes of the study.

What to Include in the Study Rationale

Although every study rationale is different and discusses different specific elements of a study’s method or approach, there are some elements that should be included to write a good rationale. Make sure to touch on the following:

• A summary of conclusions from your review of the relevant literature
• What is currently unknown (gaps in knowledge)
• Inconclusive or contested results  from previous studies on the same or similar topic
• The necessity to improve or build on previous research, such as to improve methodology or utilize newer techniques and/or technologies

There are different types of limitations that you can use to justify the need for your study. In applied/practical research, the justification for investigating something is always that an existing process/practice has a problem or is not satisfactory. Let’s say, for example, that people in a certain country/city/community commonly complain about hospital care on weekends (not enough staff, not enough attention, no decisions being made), but you looked into it and realized that nobody ever investigated whether these perceived problems are actually based on objective shortages/non-availabilities of care or whether the lower numbers of patients who are treated during weekends are commensurate with the provided services.

In this case, “lack of data” is your justification for digging deeper into the problem. Or, if it is obvious that there is a shortage of staff and provided services on weekends, you could decide to investigate which of the usual procedures are skipped during weekends as a result and what the negative consequences are. 

In basic/theoretical research, lack of knowledge is of course a common and accepted justification for additional research—but make sure that it is not your only motivation. “Nobody has ever done this” is only a convincing reason for a study if you explain to the reader why you think we should know more about this specific phenomenon. If there is earlier research but you think it has limitations, then those can usually be classified into “methodological”, “contextual”, and “conceptual” limitations. To identify such limitations, you can ask specific questions and let those questions guide you when you explain to the reader why your study was necessary:

Methodological limitations

• Did earlier studies try but failed to measure/identify a specific phenomenon?
• Was earlier research based on incorrect conceptualizations of variables?
• Were earlier studies based on questionable operationalizations of key concepts?
• Did earlier studies use questionable or inappropriate research designs?

Contextual limitations

• Have recent changes in the studied problem made previous studies irrelevant?
• Are you studying a new/particular context that previous findings do not apply to?

Conceptual limitations

• Do previous findings only make sense within a specific framework or ideology?

Study Rationale Examples

Let’s look at an example from one of our earlier articles on the statement of the problem to clarify how your rationale fits into your introduction section. This is a very short introduction for a practical research study on the challenges of online learning. Your introduction might be much longer (especially the context/background section), and this example does not contain any sources (which you will have to provide for all claims you make and all earlier studies you cite)—but please pay attention to how the background presentation , rationale, and problem statement blend into each other in a logical way so that the reader can follow and has no reason to question your motivation or the foundation of your research.

Background presentation

Since the beginning of the Covid pandemic, most educational institutions around the world have transitioned to a fully online study model, at least during peak times of infections and social distancing measures. This transition has not been easy and even two years into the pandemic, problems with online teaching and studying persist (reference needed) . 

While the increasing gap between those with access to technology and equipment and those without access has been determined to be one of the main challenges (reference needed) , others claim that online learning offers more opportunities for many students by breaking down barriers of location and distance (reference needed) .  

Rationale of the study

Since teachers and students cannot wait for circumstances to go back to normal, the measures that schools and universities have implemented during the last two years, their advantages and disadvantages, and the impact of those measures on students’ progress, satisfaction, and well-being need to be understood so that improvements can be made and demographics that have been left behind can receive the support they need as soon as possible.

Statement of the problem

To identify what changes in the learning environment were considered the most challenging and how those changes relate to a variety of student outcome measures, we conducted surveys and interviews among teachers and students at ten institutions of higher education in four different major cities, two in the US (New York and Chicago), one in South Korea (Seoul), and one in the UK (London). Responses were analyzed with a focus on different student demographics and how they might have been affected differently by the current situation.

How long is a study rationale?

In a research article bound for journal publication, your rationale should not be longer than a few sentences (no longer than one brief paragraph). A  dissertation or thesis  usually allows for a longer description; depending on the length and nature of your document, this could be up to a couple of paragraphs in length. A completely novel or unconventional approach might warrant a longer and more detailed justification than an approach that slightly deviates from well-established methods and approaches.

Summary of the research design

Example research proposal introductions.

This topic outlines the steps in the introduction of the research proposal. As discussed in the first topic in this series of web resources, there are three key elements or conceptual steps within the main body of the research proposal. In this resource, these elements are referred to as the research justification, the literature review and the research design. These three steps also structure, typically, but not always in this order, the proposal introduction which contains an outline of the proposed research.

These steps pertain to the key questions of reviewers:

• What problem or issue does the research address? (research justification)
• How will the research contribute to existing knowledge? (the 'gap' in the literature, sometimes referred to as the research 'significance')
• How will the research achieve its stated objectives? (the research design)

Reviewers look to find a summary of the case for the research in the introduction, which, in essence, involves providing summary answers to each of the questions above.

The introduction of the research proposal usually includes the following content:

• a research justification or statement of a problem (which also serves to introduce the topic)
• a summary of the key point in the literature review (a summary of what is known and how the research aims to contribute to what is known)
• the research aim or objective
• a summary of the research design
• concise definitions of any contested or specialised terms that will be used throughout the proposal (provided the first time the term is used).

This topic will consider how to write about each of these in turn.

Signaling the topic in the first sentence

The first task of the research proposal is to signal the area of the research or 'topic' so the reader knows what subject will be discussed in the proposal. This step is ideally accomplished in the opening sentence or the opening paragraph of the research proposal. It is also indicated in the title of the research proposal. It is important not to provide tangential information in the opening sentence or title because this may mislead the reader about the core subject of the proposal.

A ‘topic’ includes:

• the context or properties of the subject (the particular aspect or properties of the subject that are of interest).

Questions to consider in helping to clarify the topic:

• What is the focus of my research?
• What do I want to understand?
• What domain/s of activity does it pertain to?
• What will I investigate in order to shed light on my focus?

The research justification or the ‘problem’ statement

The goal of the first step of the research proposal is to get your audience's attention; to show them why your research matters, and to make them want to know more about your research. The first step within the research proposal is sometimes referred to as the research justification or the statement of the 'problem'. This step involves providing the reader with critical background or contextual information that introduces the topic area, and indicates why the research is important. Research proposals often open by outlining a central concern, issue, question or conundrum to which the research relates.

The research justification should be provided in an accessible and direct manner in the introductory section of the research proposal. The number of words required to complete this first conceptual step will vary widely depending on the project.

Writing about the research justification, like writing about the literature and your research design, is a creative process involving careful decision making on your part. The research justification should lead up to the topic of your research and frame your research, and, when you write your thesis, exegesis or journal article conclusion, you will again return to the research justification to wrap up the implications of your research. That is to say, your conclusions will refer back to the problem and reflect on what the findings suggest about how we should treat the problem. For this reason, you may find the need to go back and reframe your research justification as your research and writing progresses.

The most common way of establishing the importance of the research is to refer to a real world problem. Research may aim to produce knowledge that will ultimately be used to:

• advance national and organisational goals (health, clean environment, quality education),
• improve policies and regulations,
• manage risk,
• contribute to economic development,
• promote peace and prosperity,
• promote democracy,
• test assumptions (theoretical, popular, policy) about human behaviour, the economy, society,
• understand human behaviour, the economy and social experience,
• understand or critique social processes and values.

Examples of 'research problems' in opening sentences and paragraphs of research writing

Management The concept of meritocracy is one replicated and sustained in much discourse around organisational recruitment, retention and promotion. Women have a firm belief in the concept of merit, believing that hard work, education and talent will in the end be rewarded (McNamee and Miller, 2004). This belief in workplace meritocracy could in part be due to the advertising efforts of employers themselves, who, since the early 1990s, attempt to attract employees through intensive branding programs and aggressive advertising which emphasise equality of opportunity. The statistics, however, are less than convincing, with 2008 data from the Equal Employment for Women in the Workplace agency signalling that women are disproportionately represented in senior management levels compared to men, and that the numbers of women at Chief Executive Officer level in corporate Australia have actually decreased (Equal Opportunity for Women Agency, 2008). Women, it seems, are still unable to shatter the glass ceiling and are consistently overlooked at executive level.

Psychology Tension-type headache is extremely prevalent and is associated with significant personal and social costs.

Education One of the major challenges of higher education health programs is developing the cognitive abilities that will assist undergraduate students' clinical decision making. This is achieved by stimulating enquiry analysis, creating independent judgement and developing cognitive skills that are in line with graduate practice (Hollingworth and McLoughlin 2001; Bedard, 1996).

Visual arts In the East, the traditional idea of the body was not as something separate from the mind. In the West, however, the body is still perceived as separate, as a counterpart of the mind. The body is increasingly at the centre of the changing cultural environment, particularly the increasingly visual culture exemplified by the ubiquity of the image, the emergence of virtual reality, voyeurism and surveillance culture. Within the contemporary visual environment, the body's segregation from the mind has become more intense than ever, conferring upon the body a 'being watched' or 'manufacturable' status, further undermining the sense of the body as an integral part of our being.

Literature review summary

The next step following the research justification in the introduction is the literature review summary statement. This part of the introduction summarises the literature review section of the research proposal, providing a concise statement that signals the field of research and the rationale for the research question or aim.

It can be helpful to think about the literature review element as comprised of four parts. The first is a reference to the field or discipline the research will contribute to. The second is a summary of the main questions, approaches or accepted conclusions in your topic area in the field or discipline at present ('what is known'). This summary of existing research acts as a contrast to highlight the significance of the third part, your statement of a 'gap'. The fourth part rephrases this 'gap' in the form of a research question, aim, objective or hypothesis.

For example

Scholars writing about ... (the problem area) in the field of ... (discipline or sub-discipline, part one) have observed that ... ('what is known', part two). Others describe ... ('what is known', part two). A more recent perspective chronicles changes that, in broad outline, parallel those that have occurred in ... ('what is known', part two). This study differs from these approaches in that it considers ... ('gap', research focus, part three). This research draws on ... to consider ... (research objective, part four).  

More information about writing these four parts of the literature review summary is provided below.

1. The 'field' of literature

The field of research is the academic discipline within which your research is situated, and to which it will contribute. Some fields grow out of a single discipline, others are multidisciplinary. The field or discipline is linked to university courses and research, academic journals, conferences and other academic associations, and some book publishers. It also describes the expertise of thesis supervisors and examiners. 

The discipline defines the kinds of approaches, theories, methods and styles of writing adopted by scholars and researchers working within them.

For a list of academic disciplines have a look at the wikipedia site at: https://en.wikipedia.org/wiki/List_of_academic_disciplines

The field or discipline is not the same as the topic of the research. The topic is the subject matter or foci of your research. Disciplines or 'fields' refer to globally recognised areas of research and scholarship.

The field or discipline the research aims to contribute to can be signalled in a few key words within the literature review summary, or possibly earlier withn the research justification.

Sentence stems to signal the field of research 

• Within the field of ... there is now agreement that ... .
• The field of ... is marked by ongoing debate about ... .
• Following analysis of ... the field of ... turned to an exploration of ... .

2. A summary of contrasting areas of research or what is 'known'

The newness or significance of what you are doing is typically established in a contrast or dialogue with other research and scholarship. The 'gap' (or hole in the donut) only becomes apparent by the surrounding literature (or donut). Sometimes a contrast is provided to show that you are working in a different area to what has been done before, or to show that you are building on previous work, or perhaps working on an unresolved issue within a discipline. It might also be that the approaches of other disciplines on the same problem area or focus are introduced to highlight a new angle on the topic.

3. The summary of the 'gap' in the literature

The 'gap' in the field typically refers to the explanation provided to support the research question. Questions or objectives grow out of areas of uncertainty, or gaps, in the field of research. In most cases, you will not know what the gap in knowledge is until you have reviewed the literature and written up a good part of the literature review section of the proposal. It is often not possible therefore to confidently write the 'gap' statement until you have done considerable work on the literature review. Once your literature review section is sufficiently developed, you can summarise the missing piece of knowledge in a brief statement in the introduction.

Sentence stems for summarising a 'gap' in the literature

Indicate a gap in the previous research by raising a question about it, or extending previous knowledge in some way:

• However, there is little information/attention/work/data/research on … .
• However, few studies/investigations/researchers/attempt to … .

Often steps two and three blend together in the same sentence, as in the sentence stems below.

Sentence stems which both introduce research in the field (what is 'known') and summarise a 'gap'

• The research has tended to focus on …(introduce existing field foci), rather than on … ('gap').
• These studies have emphasised that … …(introduce what is known), but it remains unclear whether … ('gap').
• Although considerable research has been devoted to … (introduce field areas), rather less attention has been paid to … ('gap').

The 'significance' of the research

When writing the research proposal, it is useful to think about the research justification and the  ‘gap in the literature’ as two distinct conceptual elements, each of which must be established separately. Stating a real world problem or outlining a conceptual or other conundrum or concern is typically not, in itself, enough to justify the research. Similarly, establishing that there is a gap in the literature is often not enough on its own to persuade the reader that the research is important. In the first case, reviewers may still wonder ‘perhaps the problem or concern has already been addressed in the literature’, or, in the second, ‘so little has been done on this focus, but perhaps the proposed research is not important’? The proposal will ideally establish that the research is important, and that it will provide something new to the field of knowledge.

In effect, the research justification and the literature review work together to establish the benefit, contribution or 'significance' of the research. The 'significance' of the research is established not in a statement to be incorporated into the proposal, but as something the first two sections of the proposal work to establish. Research is significant when it pertains to something important, and when it provides new knowledge or insights within a field of knowledge.

4. The research aim or objective

The research aim is usually expressed as a concise statement at the close of the literature review. It may be referred to as an objective, a question or an aim. These terms are often used interchangeably to refer to the focus of the investigation. The research focus is the question at the heart of the research, designed to produce new knowledge. To avoid confusing the reader about the purpose of the research it is best to express it as either an aim, or an objective, or a question. It is also important to frame the aims of the research in a succinct manner; no more than three dot points say. And the aim/objective/question should be framed in more or less the same way wherever it appears in the proposal. This ensures the research focus is clear.

Language use

Research generally aims to produce knowledge, as opposed to say recommendations, policy or social change. Research may support policy or social change, and eventually produce it in some of its applications, but it does not typically produce it (with the possible exception of action research). For this reason, aims and objectives are framed in terms of knowledge production, using phrases like:

• to increase understanding, insight, clarity;
• to evaluate and critique;
• to test models, theory, or strategies.

These are all knowledge outcomes that can be achieved within the research process.

Reflecting your social philosophy in the research aim

A well written research aim typically carries within it information about the philosophical approach the research will take, even if the researcher is not themselves aware of it, or if the proposal does not discuss philosophy or social theory at any length. If you are interested in social theory, you might consider framing your aim such that it reflects your philosophical or theoretical approach. Since your philosophical approach reflects your beliefs about how 'valid' knowledge can be gained, and therefore the types of questions you ask, it follows that it will be evident within your statement of the research aim. Researchers, variously, hold that knowledge of the world arises through:

• observations of phenomena (measurements of what we can see, hear, taste, touch);
• the interactions between interpreting human subjects and objective phenomena in the world;
• ideology shaped by power, which we may be unconscious of, and which must be interrogated and replaced with knowledge that reflects people's true interests; 
• the structure of language and of the unconscious;
• the play of historical relations between human actions, institutional practices and prevailing discourses;
• metaphoric and other linguistic relations established within language and text.

The philosophical perspective underpinning your research is then reflected in the research aim. For example, depending upon your philosophical perspective, you may aim to find out about:

• observable phenomenon or facts;
• shared cultural meanings of practices, rituals, events that determine how objective phenomena are interpreted and experienced;
• social structures and political ideologies that shape experience and distort authentic or empowered experience;
• the structure of language;
• the historical evolution of networks of discursive and extra-discursive practices;
• emerging or actual phenomenon untainted by existing representation.

You might check your aim statement to ensure it reflects the philosophical perspective you claim to adopt in your proposal. Check that there are not contradictions in your philosophical claims and that you are consistent in your approach. For assistance with this you may find the Social philosophy of research resources helpful.

Sentence stems for aims and objectives

• The purpose of this research project is to … .
• The purpose of this investigation is to … .
• The aim of this research project is to … .
• This study is designed to … .

The next step or key element in the research proposal is the research design. The research design explains how the research aims will be achieved. Within the introduction a summary of the overall research design can make the project more accessible to the reader.

The summary statement of the research design within the introduction might include:

• the method/s that will be used (interviews, surveys, video observation, diary recording);
• if the research will be phased, how many phases, and what methods will be used in each phase;
• brief reference to how the data will be analysed.

The statement of the research design is often the last thing discussed in the research proposal introduction.

NB. It is not necessary to explain that a literature review and a detailed ouline of the methods and methodology will follow because academic readers will assume this.

Further examples can be found at the end of this topic, and in the drop down for this topic in the left menu. 

In summary, the introduction contains a problem statement, or explanation of why the research is important to the world, a summary of the literature review, and a summary of the research design. The introduction enables the reviewer, as well as yourself and your supervisory team, to assess the logical connections between the research justification, the 'gap' in the literature, research aim and the research design without getting lost in the detail of the project. In this sense, the introduction serves as a kind of map or abstract of the proposed research as well as of the main body of the research proposal.

The following questions may be useful in assessing your research proposal introduction.

• Have I clearly signalled the research topic in the key words and phrases used in the first sentence and title of the research proposal?
• Have I explained why my research matters, the problem or issue that underlies the research in the opening sentences,  paragraphs and page/s?
• Have I used literature, examples or other evidence to substantiate my understanding of the key issues?
• Have I explained the problem in a way that grabs the reader’s attention and concern?
• Have I indicated the field/s within which my research is situated using key words that are recognised by other scholars?
• Have I provided a summary of previous research and outlined a 'gap' in the literature?
• Have I provided a succinct statement of the objectives or aims of my research?
• Have I provided a summary of the research phases and methods?

• What makes good justification?

A justification is the reason why your thesis is valid. In economics, this typically involves explaining a theory which leads to the conclusion of your thesis.

A justification (theory) can come in many different forms:

A theoretical proposition can be explained in prose. This can be appropriate for simple concepts, but is often imprecise and it is a rare academic paper that does not rely on something more rigorous.

An example of a justification that can be satisfactorily described in words might be ‘an increase in income will lead to an increase in demand for normal goods’ (although even here an indifference curve diagram would make the same point with a greater degree of rigour).

b) Diagrams .

Familiar to all A-level students (and all undergraduates after the first week of lectures), diagrams are a simple way of presenting a theory and explaining what happens. You can clearly show why an individual’s labour supply curve might ‘bend backwards’ at high levels of income with an indifference curve diagram to explain the work/leisure tradeoff precisely.

An example of an appropriate justification using diagrams would be showing that firms in a perfectly competitive market set prices equal to marginal cost in the long run .

c) Mathematics .

There are two possibilities here. First, you can derive a simple mathematical result yourself, and discuss the implications of it. Second, you can state an equation and discuss the implications of it.

A simple example of the first would be to show that monopolies set prices above marginal cost. Let:

π(q) = p(q) – c(q) where π(q) is profit , p(q) is price, q is quantity and c(q) is cost

p = c'(q) – p'(q)q by taking derivatives with respect to q and setting π'(q)=0

And as dp / dq <0 for a monopoly selling ordinary goods  ⇒ p > c'(q)

Actually, this can also be shown by a diagram – but in many other examples, maths is clearer. These might include accurate exposition of the principal-agent problem.
