theses vs dissertation

Thesis Vs. Dissertation — Know the difference and similarities!

The academic world is filled with many different types of writing assignments, each with its own unique set of requirements and expectations. One common source of confusion for students is the distinction between a thesis and a dissertation. Both are long-form academic works, but there are several key differences between the two that are important to understand.

In Shakespeare’s day, a candidate for a master’s degree would write a thesis, an original paper in which he maintained a certain proposition. Whereas, completion of a doctoral program required submission and defense of a dissertation. He would read his thesis to his committee, after which he sat in silence while two faculty members gave point-by-point refutations of everything the candidate said.

The focus here was on the student’s ideas and his ability to arrange and express them clearly. If a student wished to advance further in academia he could pursue a dissertation. This was more of a  literature review . He would read widely in a particular area and write up his findings, discussing the various authorities and their opinions. The point was to demonstrate that he was well-versed in the literature of the field. While the confusion between the two terms is understandable, we shall tackle the dissertation vs. thesis topic in this article and provide unambiguous insights on it.

What Is a Thesis?

A thesis is a critically written scholarly piece of research work. Typically, it is submitted by students graduating from a master’s program. The purpose of a thesis is to allow students to showcase their knowledge and expertise within the subject matter they have been studying as part of the program.

What Is a Dissertation?

A dissertation is a comparatively lengthier piece of scholarly writing that accounts for your research work throughout the doctoral program. A researcher earns the Ph.D. after submitting and defending his/her dissertation. It includes all information about the original research or expanded research on a new or existing topic conducted by the Ph.D. candidate.

Dissertation vs. Thesis: Differences

• The primary difference between a thesis and a dissertation is the time when they are completed. As mentioned earlier, a thesis is presented at the culmination of a master’s program, whereas, a dissertation is presented to earn a Ph.D.
• A thesis is a compilation of research ensuring that the researcher is well-informed and has knowledge about the research topic learned in the study program. On the other hand, a dissertation provides an opportunity for the researcher to contribute new theories and information to the existing literature in the research field.
• A thesis is a presentation of learned and existing information, while the purpose of a dissertation is to develop a unique concept and defend it based on theoretical and practical results.
• A master’s thesis is approximately 100 pages in length. However, a Ph.D. dissertation should be much longer than a thesis and must include background and research information. A dissertation must include your research proposal, grant proposal, literature review , ideation of research topic, and every other minute detail about your research. Ideally, a dissertation inclusive of all details mentioned above should be three times the length of a master’s thesis.

Dissertation vs. Thesis: Similarities

• Both a thesis and a dissertation are considered final projects and are required to graduate from respective programs.
• The thesis and dissertation both require a deep and accurate understanding of the research problem.
• Both forms of scholarly written pieces must address specific research questions.
• Academic writing skills are imperative for a thesis as well as a dissertation.
• Ethical practices must be followed while collating and documenting research data.
• Plagiarism is not accepted in either.
• Both require analytical skills to support the findings.
• It is essential that both undergo intense dissertation/ thesis editing  and  critical proofreading  before final submission.

Dissertation vs. Thesis: Europe

In Europe, the original distinction between a thesis and a dissertation has been largely retained. A doctoral thesis is a focused piece of original research that is performed to obtain a Ph.D. A dissertation is part of a broader post-graduate research project.

However, the thesis has evolved since original research nowadays requires plenty of background research . So, a thesis will contain extensive citations and references to earlier work, although the focus remains on the original work that comes out of it.

Dissertation vs. Thesis: USA

In the United States, the definition of a thesis is almost the opposite of that in Europe. Because a thesis is shorter than a dissertation it gradually came to mean a preliminary degree on the way to a doctorate. A thesis is now performed to earn a Master’s degree. In scientific fields, a master’s candidate takes advanced coursework and gains hands-on experience in a research project but does not direct the project to the same extent that he would in a doctoral program. In a master’s project, the student’s ideas are welcomed and expected but the focus is on obtaining technical expertise, not doing original research. Engineering students commonly obtain Master’s degrees and seldom go on to get PhDs. In other fields such as Chemistry, the opposite is true, with a Master’s degree no longer being required as the first step for a doctorate. Almost everyone I know who received a Master’s degree in Chemistry got one because they dropped out of graduate school and wrote their truncated research as a Master’s project.

In a Nutshell

Needless to say, the dissertation vs. thesis facts are real. Therefore, using one term instead of another is not acceptable as an academic. One must remember the purpose of each and use them accordingly. However, one is not undermined by the other. Whether you are writing a thesis or a dissertation, both must be done with the same seriousness. Both require critical technical and soft skills. Improving your time management and academic writing skills plays a major role in acing both forms of scholarly writing.

How do you decipher dissertation vs. thesis? Should the interchanged usage of these terms be acceptable? How is your approach to writing a thesis different from that of a dissertation? What are the other differences associated with the thesis and dissertation? Let us know in the comments section below!

Frequently Asked Questions

"Dissertation" and "thesis" are used interchangeably but differ in: Academic Level: Thesis for master's, dissertation for doctoral degrees (US). Scope and Depth: Thesis shorter, demonstrates mastery; dissertation extensive, original research. Originality: Thesis may involve original analysis; dissertation presents significant new insights. Time and Effort: Dissertations require more resources and time than theses.

The length of a dissertation varies depending on factors like academic discipline, research topic, institution, and country. Generally, dissertations are longer than theses, ranging from 10,000 to over 100,000 words. However, word count alone does not reflect the quality or depth of the research. Guidelines from the academic institution should be consulted for specific requirements.

The length of a thesis varies depending on factors like academic discipline, research topic, institution, and country. Generally, the word count ranges from around 10,000 to 50,000 words. Specific guidelines from the academic institution should be consulted for precise requirements.

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.

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.

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

What’s the Difference Between a Dissertation vs. Thesis?

If you plan to pursue an advanced degree, you may be wondering about the differences between dissertation vs. thesis projects.

Most candidates in master’s or PhD programs are required to complete a final project in the form of a thesis or dissertation before graduating.

Editorial Listing ShortCode:

Because both a master’s thesis and a doctoral dissertation consist of in-depth research, analysis, and writing, some people use the terms interchangeably. They are separate assignments, though, that are completed at different stages in a student’s academic journey.

What’s the Difference Between a Dissertation vs. Thesis?

Students enrolled in masters degree programs typically write a thesis, whereas doctoral students complete a dissertation.

Although these projects are both research-based and are usually required for graduation, they have different lengths, requirements, and timeframes. Knowing how to distinguish between them is vital for anyone hoping to attend graduate school.

What Is a Thesis?

A thesis is a scholarly paper that many students write before completing their master’s programs. Most graduate schools require students to submit a thesis that reflects the breadth and depth of their knowledge of the field and demonstrates their advanced research skills.

To create a thesis, students begin by selecting a topic of interest and conducting extensive research in that area. That information serves as the basis for a lengthy paper that describes the student’s position on the subject and presents evidence proving their assertion. Although it’s not common, some undergraduate schools also require students to write a short thesis.

What Is a Dissertation?

A dissertation is a doctoral-level project that is a standard feature of PhD programs. When completing a dissertation, a student will conduct original or expanded research that can contribute to their field and solidify their status as a scholar.

So, what’s a dissertation and how long does it take to write one? Dissertations are often hundreds of pages in length and are completed over several years. They reflect that a student not only understands the current state of the field but also has a unique approach to the subject matter. After writing a dissertation, a student must defend it to a committee and faculty chair, who determine whether it is acceptable.

A number of universities now offer doctorate programs without dissertations but have a capstone project for completion. Common programs are DBA degrees or doctoral programs in education with no dissertation online or on campus.

Differences Between a Dissertation vs. Thesis

A dissertation and thesis are distinct in important ways, including:

• Academic level . A thesis is generally the final project required for a master’s degree. Students complete a dissertation during their doctoral programs.
• Research requirements . Writing a thesis involves reviewing and compiling information from reputable sources. To complete a dissertation, students must also present new information based on original research.
• Length . The difference in the length of a PhD dissertation vs. masters thesis is noteworthy. A thesis is typically between 50 and 100 pages in length and is written during the final year of a master’s degree program. A dissertation is generally 100 to 400 pages long and may involve several years of work.
• Completion process . Students submit their thesis projects to a group of two or more faculty mentors. Dissertation projects culminate with an oral defense, where the student answers questions from a committee of various faculty members.

The difference between dissertation and thesis projects depends on where you’re studying. For instance, in the United Kingdom, master’s students complete a dissertation, and PhD students write a doctoral thesis.

Similarities Between a Thesis vs. Dissertation

Much like the similarity between a dissertation vs. capstone , a thesis is usually accomplished as a partial requirement for an academic degree. A thesis and a dissertation usually share these common features:

• Purpose . Thesis and dissertation projects are designed to indicate whether a student is ready to graduate.
• Required skills . To successfully write a dissertation or thesis, students often have strong writing, analytical, research, and editing skills.
• Process . To complete either project, students select a focused research area, review existing sources, and write a long paper summarizing their findings and analysis.
• Expectations . Students cannot commit plagiarism or act unethically.
• Benefits . Completing a thesis or dissertation helps students gain a more thorough understanding of their field, narrow down their career goals, and demonstrate their achievements.

If you intend to complete a doctoral dissertation, you may have the opportunity to expand on the research from your master’s thesis or select a new area of interest.

Theses and Dissertations

There may be a difference between a thesis and a dissertation in terms of when students complete them, how long they are, and what type of research they involve, but they are both beneficial academically and professionally.

These projects provide students with an opportunity to gain expertise in their fields and prepare for their careers. Graduates also sometimes publish their work as journal articles or books. Having a record of publications may strengthen your candidacy for future positions. Writing a dissertation or thesis is challenging, but it can be a valuable experience.
