What Is a Thesis? | Ultimate Guide & Examples

Published on September 14, 2022 by Tegan George . Revised on November 21, 2023.

A thesis is a type of research paper based on your original research. It is usually submitted as the final step of a master’s program or a capstone to a bachelor’s degree.

Writing a thesis can be a daunting experience. Other than a dissertation , it is one of the longest pieces of writing students typically complete. It relies on your ability to conduct research from start to finish: choosing a relevant topic , crafting a proposal , designing your research , collecting data , developing a robust analysis, drawing strong conclusions , and writing concisely .

You may have heard the word thesis as a standalone term or as a component of academic writing called a thesis statement . Keep in mind that these are two very different things.

• A thesis statement is a very common component of an essay, particularly in the humanities. It usually comprises 1 or 2 sentences in the introduction of your essay , and should clearly and concisely summarize the central points of your academic essay .
• A thesis is a long-form piece of academic writing, often taking more than a full semester to complete. It is generally a degree requirement for Master’s programs, and is also sometimes required to complete a bachelor’s degree in liberal arts colleges.
• In the US, a dissertation is generally written as a final step toward obtaining a PhD.
• In other countries (particularly the UK), a dissertation is generally written at the bachelor’s or master’s level.

The final structure of your thesis depends on a variety of components, such as:

• Your discipline
• Your theoretical approach

Humanities theses are often structured more like a longer-form essay . Just like in an essay, you build an argument to support a central thesis.

In both hard and social sciences, theses typically include an introduction , literature review , methodology section ,  results section , discussion section , and conclusion section . These are each presented in their own dedicated section or chapter. In some cases, you might want to add an appendix .

Thesis examples

We’ve compiled a short list of thesis examples to help you get started.

• Example thesis #1:   “Abolition, Africans, and Abstraction: the Influence of the ‘Noble Savage’ on British and French Antislavery Thought, 1787-1807” by Suchait Kahlon.
• Example thesis #2: “’A Starving Man Helping Another Starving Man’: UNRRA, India, and the Genesis of Global Relief, 1943-1947″ by Julian Saint Reiman.

The very first page of your thesis contains all necessary identifying information, including:

• Your full title
• Your full name
• Your department
• Your institution and degree program
• Your submission date.

Sometimes the title page also includes your student ID, the name of your supervisor, or the university’s logo. Check out your university’s guidelines if you’re not sure.

Read more about title pages

The acknowledgements section is usually optional. Its main point is to allow you to thank everyone who helped you in your thesis journey, such as supervisors, friends, or family. You can also choose to write a preface , but it’s typically one or the other, not both.

Professional editors proofread and edit your paper by focusing on:

• Academic style
• Vague sentences
• Style consistency

An abstract is a short summary of your thesis. Usually a maximum of 300 words long, it’s should include brief descriptions of your research objectives , methods, results, and conclusions. Though it may seem short, it introduces your work to your audience, serving as a first impression of your thesis.

Read more about abstracts

A table of contents lists all of your sections, plus their corresponding page numbers and subheadings if you have them. This helps your reader seamlessly navigate your document.

Your table of contents should include all the major parts of your thesis. In particular, don’t forget the the appendices. If you used heading styles, it’s easy to generate an automatic table Microsoft Word.

While not mandatory, if you used a lot of tables and/or figures, it’s nice to include a list of them to help guide your reader. It’s also easy to generate one of these in Word: just use the “Insert Caption” feature.

Read more about lists of figures and tables

If you have used a lot of industry- or field-specific abbreviations in your thesis, you should include them in an alphabetized list of abbreviations . This way, your readers can easily look up any meanings they aren’t familiar with.

Relatedly, if you find yourself using a lot of very specialized or field-specific terms that may not be familiar to your reader, consider including a glossary . Alphabetize the terms you want to include with a brief definition.

An introduction sets up the topic, purpose, and relevance of your thesis, as well as expectations for your reader. This should:

• Ground your research topic , sharing any background information your reader may need
• Define the scope of your work
• Introduce any existing research on your topic, situating your work within a broader problem or debate
• State your research question(s)
• Outline (briefly) how the remainder of your work will proceed

In other words, your introduction should clearly and concisely show your reader the “what, why, and how” of your research.

Read more about introductions

A literature review helps you gain a robust understanding of any extant academic work on your topic, encompassing:

• Selecting relevant sources
• Determining the credibility of your sources
• Critically evaluating each of your sources
• Drawing connections between sources, including any themes, patterns, conflicts, or gaps

A literature review is not merely a summary of existing work. Rather, your literature review should ultimately lead to a clear justification for your own research, perhaps via:

• Addressing a gap in the literature
• Building on existing knowledge to draw new conclusions
• Exploring a new theoretical or methodological approach
• Introducing a new solution to an unresolved problem
• Definitively advocating for one side of a theoretical debate

Read more about literature reviews

Theoretical framework

Your literature review can often form the basis for your theoretical framework, but these are not the same thing. A theoretical framework defines and analyzes the concepts and theories that your research hinges on.

Read more about theoretical frameworks

Your methodology chapter shows your reader how you conducted your research. It should be written clearly and methodically, easily allowing your reader to critically assess the credibility of your argument. Furthermore, your methods section should convince your reader that your method was the best way to answer your research question.

A methodology section should generally include:

• Your overall approach ( quantitative vs. qualitative )
• Your research methods (e.g., a longitudinal study )
• Your data collection methods (e.g., interviews or a controlled experiment
• Any tools or materials you used (e.g., computer software)
• The data analysis methods you chose (e.g., statistical analysis , discourse analysis )
• A strong, but not defensive justification of your methods

Read more about methodology sections

Your results section should highlight what your methodology discovered. These two sections work in tandem, but shouldn’t repeat each other. While your results section can include hypotheses or themes, don’t include any speculation or new arguments here.

Your results section should:

• State each (relevant) result with any (relevant) descriptive statistics (e.g., mean , standard deviation ) and inferential statistics (e.g., test statistics , p values )
• Explain how each result relates to the research question
• Determine whether the hypothesis was supported

Additional data (like raw numbers or interview transcripts ) can be included as an appendix . You can include tables and figures, but only if they help the reader better understand your results.

Read more about results sections

Your discussion section is where you can interpret your results in detail. Did they meet your expectations? How well do they fit within the framework that you built? You can refer back to any relevant source material to situate your results within your field, but leave most of that analysis in your literature review.

For any unexpected results, offer explanations or alternative interpretations of your data.

Read more about discussion sections

Your thesis conclusion should concisely answer your main research question. It should leave your reader with an ultra-clear understanding of your central argument, and emphasize what your research specifically has contributed to your field.

Why does your research matter? What recommendations for future research do you have? Lastly, wrap up your work with any concluding remarks.

Read more about conclusions

In order to avoid plagiarism , don’t forget to include a full reference list at the end of your thesis, citing the sources that you used. Choose one citation style and follow it consistently throughout your thesis, taking note of the formatting requirements of each style.

Which style you choose is often set by your department or your field, but common styles include MLA , Chicago , and APA.

Create APA citations Create MLA citations

In order to stay clear and concise, your thesis should include the most essential information needed to answer your research question. However, chances are you have many contributing documents, like interview transcripts or survey questions . These can be added as appendices , to save space in the main body.

Read more about appendices

Once you’re done writing, the next part of your editing process begins. Leave plenty of time for proofreading and editing prior to submission. Nothing looks worse than grammar mistakes or sloppy spelling errors!

Consider using a professional thesis editing service or grammar checker to make sure your final project is perfect.

Once you’ve submitted your final product, it’s common practice to have a thesis defense, an oral component of your finished work. This is scheduled by your advisor or committee, and usually entails a presentation and Q&A session.

After your defense , your committee will meet to determine if you deserve any departmental honors or accolades. However, keep in mind that defenses are usually just a formality. If there are any serious issues with your work, these should be resolved with your advisor way before a defense.

The conclusion of your thesis or dissertation shouldn’t take up more than 5–7% of your overall word count.

If you only used a few abbreviations in your thesis or dissertation , you don’t necessarily need to include a list of abbreviations .

If your abbreviations are numerous, or if you think they won’t be known to your audience, it’s never a bad idea to add one. They can also improve readability, minimizing confusion about abbreviations unfamiliar to your reader.

When you mention different chapters within your text, it’s considered best to use Roman numerals for most citation styles. However, the most important thing here is to remain consistent whenever using numbers in your dissertation .

A thesis or dissertation outline is one of the most critical first steps in your writing process. It helps you to lay out and organize your ideas and can provide you with a roadmap for deciding what kind of research you’d like to undertake.

Generally, an outline contains information on the different sections included in your thesis or dissertation , such as:

• Your anticipated title
• Your abstract
• Your chapters (sometimes subdivided into further topics like literature review , research methods , avenues for future research, etc.)

A thesis is typically written by students finishing up a bachelor’s or Master’s degree. Some educational institutions, particularly in the liberal arts, have mandatory theses, but they are often not mandatory to graduate from bachelor’s degrees. It is more common for a thesis to be a graduation requirement from a Master’s degree.

Even if not mandatory, you may want to consider writing a thesis if you:

• Plan to attend graduate school soon
• Have a particular topic you’d like to study more in-depth
• Are considering a career in research
• Would like a capstone experience to tie up your academic experience

Thesis Statements

What this handout is about.

This handout describes what a thesis statement is, how thesis statements work in your writing, and how you can craft or refine one for your draft.

Introduction

Writing in college often takes the form of persuasion—convincing others that you have an interesting, logical point of view on the subject you are studying. Persuasion is a skill you practice regularly in your daily life. You persuade your roommate to clean up, your parents to let you borrow the car, your friend to vote for your favorite candidate or policy. In college, course assignments often ask you to make a persuasive case in writing. You are asked to convince your reader of your point of view. This form of persuasion, often called academic argument, follows a predictable pattern in writing. After a brief introduction of your topic, you state your point of view on the topic directly and often in one sentence. This sentence is the thesis statement, and it serves as a summary of the argument you’ll make in the rest of your paper.

What is a thesis statement?

A thesis statement:

• tells the reader how you will interpret the significance of the subject matter under discussion.
• is a road map for the paper; in other words, it tells the reader what to expect from the rest of the paper.
• directly answers the question asked of you. A thesis is an interpretation of a question or subject, not the subject itself. The subject, or topic, of an essay might be World War II or Moby Dick; a thesis must then offer a way to understand the war or the novel.
• makes a claim that others might dispute.
• is usually a single sentence near the beginning of your paper (most often, at the end of the first paragraph) that presents your argument to the reader. The rest of the paper, the body of the essay, gathers and organizes evidence that will persuade the reader of the logic of your interpretation.

If your assignment asks you to take a position or develop a claim about a subject, you may need to convey that position or claim in a thesis statement near the beginning of your draft. The assignment may not explicitly state that you need a thesis statement because your instructor may assume you will include one. When in doubt, ask your instructor if the assignment requires a thesis statement. When an assignment asks you to analyze, to interpret, to compare and contrast, to demonstrate cause and effect, or to take a stand on an issue, it is likely that you are being asked to develop a thesis and to support it persuasively. (Check out our handout on understanding assignments for more information.)

How do I create a thesis?

A thesis is the result of a lengthy thinking process. Formulating a thesis is not the first thing you do after reading an essay assignment. Before you develop an argument on any topic, you have to collect and organize evidence, look for possible relationships between known facts (such as surprising contrasts or similarities), and think about the significance of these relationships. Once you do this thinking, you will probably have a “working thesis” that presents a basic or main idea and an argument that you think you can support with evidence. Both the argument and your thesis are likely to need adjustment along the way.

Writers use all kinds of techniques to stimulate their thinking and to help them clarify relationships or comprehend the broader significance of a topic and arrive at a thesis statement. For more ideas on how to get started, see our handout on brainstorming .

How do I know if my thesis is strong?

If there’s time, run it by your instructor or make an appointment at the Writing Center to get some feedback. Even if you do not have time to get advice elsewhere, you can do some thesis evaluation of your own. When reviewing your first draft and its working thesis, ask yourself the following :

• Do I answer the question? Re-reading the question prompt after constructing a working thesis can help you fix an argument that misses the focus of the question. If the prompt isn’t phrased as a question, try to rephrase it. For example, “Discuss the effect of X on Y” can be rephrased as “What is the effect of X on Y?”
• Have I taken a position that others might challenge or oppose? If your thesis simply states facts that no one would, or even could, disagree with, it’s possible that you are simply providing a summary, rather than making an argument.
• Is my thesis statement specific enough? Thesis statements that are too vague often do not have a strong argument. If your thesis contains words like “good” or “successful,” see if you could be more specific: why is something “good”; what specifically makes something “successful”?
• Does my thesis pass the “So what?” test? If a reader’s first response is likely to  be “So what?” then you need to clarify, to forge a relationship, or to connect to a larger issue.
• Does my essay support my thesis specifically and without wandering? If your thesis and the body of your essay do not seem to go together, one of them has to change. It’s okay to change your working thesis to reflect things you have figured out in the course of writing your paper. Remember, always reassess and revise your writing as necessary.
• Does my thesis pass the “how and why?” test? If a reader’s first response is “how?” or “why?” your thesis may be too open-ended and lack guidance for the reader. See what you can add to give the reader a better take on your position right from the beginning.

Suppose you are taking a course on contemporary communication, and the instructor hands out the following essay assignment: “Discuss the impact of social media on public awareness.” Looking back at your notes, you might start with this working thesis:

Social media impacts public awareness in both positive and negative ways.

You can use the questions above to help you revise this general statement into a stronger thesis.

• Do I answer the question? You can analyze this if you rephrase “discuss the impact” as “what is the impact?” This way, you can see that you’ve answered the question only very generally with the vague “positive and negative ways.”
• Have I taken a position that others might challenge or oppose? Not likely. Only people who maintain that social media has a solely positive or solely negative impact could disagree.
• Is my thesis statement specific enough? No. What are the positive effects? What are the negative effects?
• Does my thesis pass the “how and why?” test? No. Why are they positive? How are they positive? What are their causes? Why are they negative? How are they negative? What are their causes?
• Does my thesis pass the “So what?” test? No. Why should anyone care about the positive and/or negative impact of social media?

After thinking about your answers to these questions, you decide to focus on the one impact you feel strongly about and have strong evidence for:

Because not every voice on social media is reliable, people have become much more critical consumers of information, and thus, more informed voters.

This version is a much stronger thesis! It answers the question, takes a specific position that others can challenge, and it gives a sense of why it matters.

Let’s try another. Suppose your literature professor hands out the following assignment in a class on the American novel: Write an analysis of some aspect of Mark Twain’s novel Huckleberry Finn. “This will be easy,” you think. “I loved Huckleberry Finn!” You grab a pad of paper and write:

Mark Twain’s Huckleberry Finn is a great American novel.

You begin to analyze your thesis:

• Do I answer the question? No. The prompt asks you to analyze some aspect of the novel. Your working thesis is a statement of general appreciation for the entire novel.

Think about aspects of the novel that are important to its structure or meaning—for example, the role of storytelling, the contrasting scenes between the shore and the river, or the relationships between adults and children. Now you write:

In Huckleberry Finn, Mark Twain develops a contrast between life on the river and life on the shore.

• Do I answer the question? Yes!
• Have I taken a position that others might challenge or oppose? Not really. This contrast is well-known and accepted.
• Is my thesis statement specific enough? It’s getting there–you have highlighted an important aspect of the novel for investigation. However, it’s still not clear what your analysis will reveal.
• Does my thesis pass the “how and why?” test? Not yet. Compare scenes from the book and see what you discover. Free write, make lists, jot down Huck’s actions and reactions and anything else that seems interesting.
• Does my thesis pass the “So what?” test? What’s the point of this contrast? What does it signify?”

After examining the evidence and considering your own insights, you write:

Through its contrasting river and shore scenes, Twain’s Huckleberry Finn suggests that to find the true expression of American democratic ideals, one must leave “civilized” society and go back to nature.

This final thesis statement presents an interpretation of a literary work based on an analysis of its content. Of course, for the essay itself to be successful, you must now present evidence from the novel that will convince the reader of your interpretation.

Stay Focused on Purpose

It is critical to keep focused on the purpose of your writing: to prove the thesis.  If you are planning an essay, start with at least a scratch outline and a working thesis – a starting thesis that you know you might change as you draft your paper.  If you are writing an essay exam or paper, be sure to identify the key terms in the instructions such as the following and don’t stray from the topic and/or question or what the instructions say to do: analyze, clarify, classify, compare, contrast, define, describe, discuss, evaluate, explain, identify, illustrate, interpret, justify, relate, summarize, support, or trace.  Remember to review and revise. See Writiing Process and Outlining in Related Pages on the right sidebar.

Relevance, Reliability, Accuracy, and Sufficiency

The information presented to prove the thesis should be relevant, reliable, credible, and sufficient.

• relevant evidence  – evidence must be directly and clearly related to proving the thesis
• reliable evidence  – evidence must be consistent and accurate; the same circumstances must have the same result
• reliable narrator  –  there is general presumption in sources that are purportedly factual is that the writer is reliable; however, that it is not necessarily accurate that the writer is presenting consistent or even accurate information even when that writer thinks he or she is.  The term  reliable narrator  is used more frequently in literary analysis to describe that the person telling the story can be trusted to be giving reliable information.
• unreliable narrator  – an unreliable narrator is where when the person writing the source is not consistent or accurate. The term  reliable narrator  is used more frequently in literary analysis to describe that the person telling the story cannot be trusted to be giving reliable information.
• accurate evidence  –  for evidence to be credible, it must be factual.  Even one inaccurate piece of information will cause the reader to doubt an author’s credibility.
• sufficient evidence  – evidence must be sufficient.  Sufficiency is a question of whether even though the evidence used to prove the thesis may be reliable and accurate, it may not be enough to prove the thesis
• representative evidence  – a consideration related to relevance, reliability, credibility, and sufficiency is whether the evidence represents the entire group involved in the analysis.  For example, evidence which is relevant, reliable, accurate, and sufficient that shows a high correlation of pesticide content in certain foods may not have been drawn from samples from all over the country, so the incidence may be limited only to the area from which the sample was drawn

Transitional Devices

A good paper must have  coherence . This means that all the ideas should be in a logical order and fit together like links in a chain.  One way to do this is to have an overall plan for how the paper will develop, such as in an outline. Another is to use transitional devices.

Transitional devices are a word or words that help one sentence or paragraph flow into the next. Here is an example of two sentences which do not have any transitional information to connect them:

The weather looked threatening. They went on their picnic.

In the above example, we are unsure how these two ideas relate to each other.  See how one word connects the two thoughts in the following example:

The weather looked threatening. Nevertheless, they went on their picnic.

Now we understand the relationship between the ideas. The word  Nevertheless  serves as a transitional device from one sentence to the next.

Transitional devices can be more than just a word. They can also be entire phrases. Here is an example of a sentence with a phrase that serves as a transitional device.

In spite of the cloudy sky, they went on their picnic.

The words  In spite of the cloudy sky  are a transitional device.

Just as there should be transitions between sentences, paragraphs should also link together. There are a few ways to do this.

• Refer to key words or thoughts from the thesis.
• Refer to key words or ideas from the preceding paragraph.
• Use transitional expressions.
• Use transitional sentences.

Using transitions in your paper is like using signals when you drive. Imagine following someone in a car who is leading you to a place you’ve never been before. Think about how difficult it would be to follow him to the correct destination if he didn’t signal! Just as in driving, you don’t want to take a turn in your paper and risk leaving your readers behind.

Facts and Statistics

Facts and statistics can be very persuasive.  In fact, a critical reader will challenge the accuracy or the legitimacy of the sources for purported facts and statistics.

It is important to investigate those ourselves before we use information that is supposed to be factual.  We should know exactly where the information comes from and evaluate whether the source is credible.  It is not a good idea to present information as though it is a fact unless you know it is a fact.

Statistics can be manipulated.  An educated audience will pick that up and you’ll lose credibility if they sense that the presentation of statistics is not honest.

Here’s an example:

A board president claimed that ninety percent of the people who responded to a survey wanted a certain action taken.  When asked how many responded to the survey, he answered that ten people had responded.

Primary and Secondary Sources

A  primary source  is a source written by the person providing the information.  If you get information from your friend, the friend is the primary source.

In research, it is preferable to get information directly from the source when it is available.

Secondary sources  are not directly from the provider of the information.  It is like getting information about what Joan said from John.  This information is not as reliable as primary sources.  However, it is common practice for authors to include what others have said in their articles and analyze what was said.

Pictures, charts, graphs, drawings, and diagrams; not appropriate in writing for all courses – check with instructor if not indicated on assignment

Rhetorical Modes as Types of Proof

Narration is the use of language to tell a story. It is the telling of a sequence of events or occurrences.  As a method of helping to prove a thesis, narration might be used tell the experience of the author or of someone else.  For example, in a paper discussing allergies, a writer might narrate his or her experiences with allergies and what was done to control exposure to the allergens or treat the symptoms.

It is important, especially when dealing with a complex topic, that you define all the key terms in your argument. This is important because not all definitions are universally agreed upon. Take the idea of immigration reform. For some this could mean providing a path to citizenship for illegal immigrants; for others, it could mean tighter border security.

How you define something influences how you and your audience see a particular issue.  Even the terms used to describe an issue can influence the reader. Take for example the difference in calling someone an “illegal immigrant” versus an “undocumented worker.”

Using the first entry in a standard dictionary is not usually sufficient, especially when writing about something very technical. Some areas have specialized dictionaries to define specific terms. The word  gross is  used very differently if used in everyday language or by a medical clinician.  In everyday language, the word  gross  means awful or disgusting.  However, in medical language the word gross means large.

Be careful not to use vague or judgmental words in your definition as it can seem to your readers that you are biased or imprecise.

Division and Classification

With complicated topics, it might helpful to separate the bigger topic or subject area into smaller parts and classify the information according to separate criteria.  For example, in discussing plants, it could help to discuss by categories of plants.

Description

Description is to help bring the reader into the writing.  Specific descriptions of sensations including sights, sounds, smell, touch, and taste can make the reader feel as though he or she is part of the experience which can be a useful strategy in proving a thesis.

Process Analysis

Using examples and facts can support your paper, but simply using these is not enough; you must also think critically about what you have read and react to it. Analysis means to go beyond the obvious and beyond what is literally in the text.

It is very tempting when writing a paper to simply paraphrase or summarize a source than it is to think critically about what was written. Often, when the source is difficult to understand, just repeating his or her words may seem simpler.

Analysis, however, requires a complete understanding of the point the author is making because you must take a complex idea, break it down in to smaller, simpler parts, and then figure out how they fit together.

Examples and Illustrations

Using examples is a way to explain or to prove that our position is accurate.  Examples can be true or actual situations or they can be hypothetical.

Using examples are more effective if they are close to or exactly the same circumstances as in the case you are trying to prove.  If a person can think to themselves that there is a significant difference, the example will not be effective.

If you are using an actual event, you should be careful to be sure you are familiar with the details.  If not, using the example can backfire and convince the person of the opposite.

If you use a hypothetical situation as an example, you should think it through completely first.  Again, if it is not a good example, it would weaken your position.

Attorneys use example to argue cases.  In fact, if they can present a previously decided case in the same jurisdiction that matches up with the existing decision, the judge must decide in their favor.  The supportive case has to be “on all fours,” that is, match up on all the essential points.

Compare/Contrast

We compare and contrast things all the time in life to make decisions from where we buy our groceries to what car to buy. Just as in life, college papers also often require comparing and contrasting. You might have to compare two historic events, world leaders, or poems. Often, even if it is not required, ideas become clearer when you evaluate them in relation to one another.

It is important to remember to be fair when contrasting ideas to show that one is superior.  If you note only the strengths of one and only the faults of the other, your readers may determine that your argument is weak or not credible.

One way to do this is to think about how they are similar in addition to how they differ.  Take the words  liberal  and  conservative  for example. Usually these are seen as very different things, but they do have similarities. They both are political philosophies, they both have a moral underpinning, and they both have people who passionately support their ideals.

Cause/Effect

Another way of proving a thesis is to show the causes and/or effects.  For example, if your thesis is that the use of wind power is the best way of producing electricity, showing the effects of how much electricity can be produced is good proof.  You could also include the bad effects of some other means of producing electricity.

Persuasion/Argumentation

In a way, all communication has a purpose: to persuade or argue for the validity of what is being said.  Even when a person is expressing an emotion, effective communication involves convincing the audience that those feelings are legitimate.

The same strategies used to develop a good writing are used when the purpose is specifically to persuade.  Transitional devices, use of examples, facts and statistics, primary and secondary sources, and rhetorical modes including analysis, definition, comparison/contrast, and cause and/or Effect are ways to prove your point.

See the difference in how these strategies can be used for persuasion.

A simple sentence:  It was a cold day.

Transitional device:  In addition to being dark and cloudy, it was a cold day.

Example:  It was so cold that the chill of the air was felt right through layers of clothing.

Facts/Statistics:  It was a record-breaking cold with temperatures plummeting below 15o F.

Primary Source:  According to Jones, “Temperatures fell as though we were entering another Ice Age.”

Secondary Source:  Goldstein agreed: “This cold wave surpasses any recorded to date” (qtd. in Jones).

Rhetorical Modes

Narration:  While I was walking in the park, I noticed that it was a cold day.

Definition:  The temperature at which water freezes is 32o F.  This is typically the temperature used to describe weather conditions as  freezing.

Description:  It was so cold that frost was forming on the windows and the leaves on the plants were curling.

Process Analysis:  The measurement of what is considered  a cold day  includes the temperature and humidity reading along with any wind-chill factor.

Comparison/Contrast:  It was so cold this year that the strawberries froze and fell to the ground whereas last year’s crop survived the freeze.

Cause/Effect:  Because it was so cold, the strawberries froze and fell to the ground.

Persuasion/Argumentation:  The reading on the thermometer of 32o F, the frost or the windows, and the curling leaves of the plants show it was a cold day.

How to Write a Strong Thesis Statement

A thesis can be found in many places—a debate speech, a lawyer’s closing argument, even an advertisement. But the most common place for a thesis statement (and probably why you’re reading this article) is in an essay.

Whether you’re writing an argumentative paper, an informative essay, or a compare/contrast statement, you need a thesis. Without a thesis, your argument falls flat and your information is unfocused. Since a thesis is so important, it’s probably a good idea to look at some tips on how to put together a strong one.

Guide Overview

What is a “thesis statement” anyway.

• 2 categories of thesis statements: informative and persuasive
• 2 styles of thesis statements
• Formula for a strong argumentative thesis
• The qualities of a solid thesis statement (video)

You may have heard of something called a “thesis.” It’s what seniors commonly refer to as their final paper before graduation. That’s not what we’re talking about here. That type of thesis is a long, well-written paper that takes years to piece together.

Instead, we’re talking about a single sentence that ties together the main idea of any argument . In the context of student essays, it’s a statement that summarizes your topic and declares your position on it. This sentence can tell a reader whether your essay is something they want to read.

2 Categories of Thesis Statements: Informative and Persuasive

Just as there are different types of essays, there are different types of thesis statements. The thesis should match the essay.

For example, with an informative essay, you should compose an informative thesis (rather than argumentative). You want to declare your intentions in this essay and guide the reader to the conclusion that you reach.

To make a peanut butter and jelly sandwich, you must procure the ingredients, find a knife, and spread the condiments.

This thesis showed the reader the topic (a type of sandwich) and the direction the essay will take (describing how the sandwich is made).

Most other types of essays, whether compare/contrast, argumentative, or narrative, have thesis statements that take a position and argue it. In other words, unless your purpose is simply to inform, your thesis is considered persuasive. A persuasive thesis usually contains an opinion and the reason why your opinion is true.

Peanut butter and jelly sandwiches are the best type of sandwich because they are versatile, easy to make, and taste good.

In this persuasive thesis statement, you see that I state my opinion (the best type of sandwich), which means I have chosen a stance. Next, I explain that my opinion is correct with several key reasons. This persuasive type of thesis can be used in any essay that contains the writer’s opinion, including, as I mentioned above, compare/contrast essays, narrative essays, and so on.

2 Styles of Thesis Statements

Just as there are two different types of thesis statements (informative and persuasive), there are two basic styles you can use.

The first style uses a list of two or more points . This style of thesis is perfect for a brief essay that contains only two or three body paragraphs. This basic five-paragraph essay is typical of middle and high school assignments.

C.S. Lewis’s Chronicles of Narnia series is one of the richest works of the 20th century because it offers an escape from reality, teaches readers to have faith even when they don’t understand, and contains a host of vibrant characters.

In the above persuasive thesis, you can see my opinion about Narnia followed by three clear reasons. This thesis is perfect for setting up a tidy five-paragraph essay.

In college, five paragraph essays become few and far between as essay length gets longer. Can you imagine having only five paragraphs in a six-page paper? For a longer essay, you need a thesis statement that is more versatile. Instead of listing two or three distinct points, a thesis can list one overarching point that all body paragraphs tie into.

Good vs. evil is the main theme of Lewis’s Narnia series, as is made clear through the struggles the main characters face in each book.

In this thesis, I have made a claim about the theme in Narnia followed by my reasoning. The broader scope of this thesis allows me to write about each of the series’ seven novels. I am no longer limited in how many body paragraphs I can logically use.

Formula for a Strong Argumentative Thesis

One thing I find that is helpful for students is having a clear template. While students rarely end up with a thesis that follows this exact wording, the following template creates a good starting point:

___________ is true because of ___________, ___________, and ___________.

Conversely, the formula for a thesis with only one point might follow this template:

___________________ is true because of _____________________.

Students usually end up using different terminology than simply “because,” but having a template is always helpful to get the creative juices flowing.

The Qualities of a Solid Thesis Statement

When composing a thesis, you must consider not only the format, but other qualities like length, position in the essay, and how strong the argument is.

Length: A thesis statement can be short or long, depending on how many points it mentions. Typically, however, it is only one concise sentence. It does contain at least two clauses, usually an independent clause (the opinion) and a dependent clause (the reasons). You probably should aim for a single sentence that is at least two lines, or about 30 to 40 words long.

Position: A thesis statement always belongs at the beginning of an essay. This is because it is a sentence that tells the reader what the writer is going to discuss. Teachers will have different preferences for the precise location of the thesis, but a good rule of thumb is in the introduction paragraph, within the last two or three sentences.

Strength: Finally, for a persuasive thesis to be strong, it needs to be arguable. This means that the statement is not obvious, and it is not something that everyone agrees is true.

Example of weak thesis:

Peanut butter and jelly sandwiches are easy to make because it just takes three ingredients.

Most people would agree that PB&J is one of the easiest sandwiches in the American lunch repertoire.

Example of a stronger thesis:

Peanut butter and jelly sandwiches are fun to eat because they always slide around.

This is more arguable because there are plenty of folks who might think a PB&J is messy or slimy rather than fun.

Composing a thesis statement does take a bit more thought than many other parts of an essay. However, because a thesis statement can contain an entire argument in just a few words, it is worth taking the extra time to compose this sentence. It can direct your research and your argument so that your essay is tight, focused, and makes readers think.

Tips for Writing Your Thesis Statement

1. Determine what kind of paper you are writing:

• An analytical paper breaks down an issue or an idea into its component parts, evaluates the issue or idea, and presents this breakdown and evaluation to the audience.
• An expository (explanatory) paper explains something to the audience.
• An argumentative paper makes a claim about a topic and justifies this claim with specific evidence. The claim could be an opinion, a policy proposal, an evaluation, a cause-and-effect statement, or an interpretation. The goal of the argumentative paper is to convince the audience that the claim is true based on the evidence provided.

If you are writing a text that does not fall under these three categories (e.g., a narrative), a thesis statement somewhere in the first paragraph could still be helpful to your reader.

2. Your thesis statement should be specific—it should cover only what you will discuss in your paper and should be supported with specific evidence.

3. The thesis statement usually appears at the end of the first paragraph of a paper.

4. Your topic may change as you write, so you may need to revise your thesis statement to reflect exactly what you have discussed in the paper.

Thesis Statement Examples

Example of an analytical thesis statement:

The paper that follows should:

• Explain the analysis of the college admission process
• Explain the challenge facing admissions counselors

Example of an expository (explanatory) thesis statement:

• Explain how students spend their time studying, attending class, and socializing with peers

Example of an argumentative thesis statement:

• Present an argument and give evidence to support the claim that students should pursue community projects before entering college

Reference management. Clean and simple.

How to proofread your thesis

1. Review your institution's guidelines

2. take a break before you read anything, 3. determine how to proofread your thesis, 4. use online tools, 5. read your thesis in a different order, 6. read your thesis out loud, 7. reach out to your peers, frequently asked questions about proofreading your thesis, related articles.

Now that you've finished your thesis , it's time to proofread it. You'll need to do this several times to ensure that you submit a solid thesis that's free of grammatical mistakes and typos. We've put together a few tips that can help you optimize the proofreading stage of your thesis.

Your institution will likely have specific guidelines for formatting your thesis. Be sure to double-check the guidelines for layout and format issues, including:

• paper size and margins
• running head
• page numbering
• line spacing

Take time to read through the guidelines again and keep them handy as you proofread your thesis.

The proofreading stage is also a good time to check your citations or references . Whether you're using Harvard, APA (American Psychological Association), MLA (Modern Language Association) or some other citation style, make sure that your citations are correct.

Give yourself some time off before you start proofreading your thesis. This allows you to return to your work with fresh eyes. Ideally, you should plan to take a break of several weeks before you begin proofreading; however, even a short break can help you refocus and catch more mistakes.

Some people like to proofread their thesis on screen, while others like to print it out and read it on paper. Whichever method you choose, be aware that you can't read it all at once. Rather, make a plan for how you want to approach proofreading and stick to it. You'll generally want to break up your process by chapter or section.

Consider breaking down your thesis proofreading process in one of these ways:

• by paragraph

Several online tools can help you with proofreading and some of them are even free. Use tools like Grammarly or Proofread Bot for proofreading or Readable.com or Slickwrite to critique your grammar and writing. A quick Google search will show you that there are dozens of tools out there that can help you with your thesis!

Week 1 : Read a chapter a day, watching out for major issues in argumentation, use of evidence, and organization.

Week 2 : Complete substantive revisions and check that all citations are correct. Use a reference manager like Paperpile to create accurate citations and bibliographies.

Week 3 : Re-read each chapter, checking for any additional surface errors. Double-check that your formatting aligns with your department’s thesis requirements.

Try reading your work backwards or in a random order. This approach often works better than reading your work from beginning to end.

By switching up your expectations, you will catch more errors. Plus, starting at the end allows you to keep your conclusions in mind as you read and helps you to verify that you've proven your thesis statement.

The best way to catch grammatical, stylistic, and organizational mistakes is to read your work aloud to yourself. Hearing your own words greatly increases your ability to find typos and errors.

Keep your eye out for the following common errors:

• subject-verb agreement
• faulty predication
• misplaced modifiers
• tense changes
• incorrect citations

If you have friends or peers who are also writing theses, or who have completed them, reach out for advice and help. For instance, blogger Pat Thomson suggests setting up a proofreading deal with a friend.

Also, you might find it useful to join or start a writing group. These groups build accountability and provide writers with support for all stages of the research and writing process.

The length of the proofreading process depends on the length of the thesis. Plus, you should plan to take a couple of weeks off before you start proofreading. It's also a good idea to break up longer projects by chapter or section.

Always double-check your institution's guidelines for the general layout, including:

If you know someone who is willing to proofread your thesis, then definitely ask! Friends and peers who are also working on theses, or who have recently finished, can provide you with useful insights about the grammar, style, and structure of your thesis.

As part of your proofreading plan, you should create a checklist of items that you want to watch out for while proofreading your thesis. Your checklist might include:

• Spelling and typos
• Verb tenses and subject-verb agreement
• Sentence structure
• Layout and formatting
• Citations and/or references
• Consistency of style
• Organization
• Overall flow

You should plan to proofread your thesis as many times as it takes to ensure that you submit a polished and professional work. Typically, however, most thesis writers proofread their work around three to four times.

Think of yourself as a member of a jury, listening to a lawyer who is presenting an opening argument. You'll want to know very soon whether the lawyer believes the accused to be guilty or not guilty, and how the lawyer plans to convince you. Readers of academic essays are like jury members: before they have read too far, they want to know what the essay argues as well as how the writer plans to make the argument. After reading your thesis statement, the reader should think, "This essay is going to try to convince me of something. I'm not convinced yet, but I'm interested to see how I might be."

An effective thesis cannot be answered with a simple "yes" or "no." A thesis is not a topic; nor is it a fact; nor is it an opinion. "Reasons for the fall of communism" is a topic. "Communism collapsed in Eastern Europe" is a fact known by educated people. "The fall of communism is the best thing that ever happened in Europe" is an opinion. (Superlatives like "the best" almost always lead to trouble. It's impossible to weigh every "thing" that ever happened in Europe. And what about the fall of Hitler? Couldn't that be "the best thing"?)

A good thesis has two parts. It should tell what you plan to argue, and it should "telegraph" how you plan to argue—that is, what particular support for your claim is going where in your essay.

Steps in Constructing a Thesis

First, analyze your primary sources.  Look for tension, interest, ambiguity, controversy, and/or complication. Does the author contradict himself or herself? Is a point made and later reversed? What are the deeper implications of the author's argument? Figuring out the why to one or more of these questions, or to related questions, will put you on the path to developing a working thesis. (Without the why, you probably have only come up with an observation—that there are, for instance, many different metaphors in such-and-such a poem—which is not a thesis.)

Once you have a working thesis, write it down.  There is nothing as frustrating as hitting on a great idea for a thesis, then forgetting it when you lose concentration. And by writing down your thesis you will be forced to think of it clearly, logically, and concisely. You probably will not be able to write out a final-draft version of your thesis the first time you try, but you'll get yourself on the right track by writing down what you have.

Keep your thesis prominent in your introduction.  A good, standard place for your thesis statement is at the end of an introductory paragraph, especially in shorter (5-15 page) essays. Readers are used to finding theses there, so they automatically pay more attention when they read the last sentence of your introduction. Although this is not required in all academic essays, it is a good rule of thumb.

Anticipate the counterarguments.  Once you have a working thesis, you should think about what might be said against it. This will help you to refine your thesis, and it will also make you think of the arguments that you'll need to refute later on in your essay. (Every argument has a counterargument. If yours doesn't, then it's not an argument—it may be a fact, or an opinion, but it is not an argument.)

This statement is on its way to being a thesis. However, it is too easy to imagine possible counterarguments. For example, a political observer might believe that Dukakis lost because he suffered from a "soft-on-crime" image. If you complicate your thesis by anticipating the counterargument, you'll strengthen your argument, as shown in the sentence below.

Some Caveats and Some Examples

A thesis is never a question.  Readers of academic essays expect to have questions discussed, explored, or even answered. A question ("Why did communism collapse in Eastern Europe?") is not an argument, and without an argument, a thesis is dead in the water.

A thesis is never a list.  "For political, economic, social and cultural reasons, communism collapsed in Eastern Europe" does a good job of "telegraphing" the reader what to expect in the essay—a section about political reasons, a section about economic reasons, a section about social reasons, and a section about cultural reasons. However, political, economic, social and cultural reasons are pretty much the only possible reasons why communism could collapse. This sentence lacks tension and doesn't advance an argument. Everyone knows that politics, economics, and culture are important.

A thesis should never be vague, combative or confrontational.  An ineffective thesis would be, "Communism collapsed in Eastern Europe because communism is evil." This is hard to argue (evil from whose perspective? what does evil mean?) and it is likely to mark you as moralistic and judgmental rather than rational and thorough. It also may spark a defensive reaction from readers sympathetic to communism. If readers strongly disagree with you right off the bat, they may stop reading.

An effective thesis has a definable, arguable claim.  "While cultural forces contributed to the collapse of communism in Eastern Europe, the disintegration of economies played the key role in driving its decline" is an effective thesis sentence that "telegraphs," so that the reader expects the essay to have a section about cultural forces and another about the disintegration of economies. This thesis makes a definite, arguable claim: that the disintegration of economies played a more important role than cultural forces in defeating communism in Eastern Europe. The reader would react to this statement by thinking, "Perhaps what the author says is true, but I am not convinced. I want to read further to see how the author argues this claim."

A thesis should be as clear and specific as possible.  Avoid overused, general terms and abstractions. For example, "Communism collapsed in Eastern Europe because of the ruling elite's inability to address the economic concerns of the people" is more powerful than "Communism collapsed due to societal discontent."
