For many people thesis or dissertation would be one and the same. That is because, a thesis or a dissertation is a document submitted in support of candidature for an academic degree or professional qualification presenting the author’s research and findings. The term dissertation can at times be used to describe a treatise without relation to obtaining an academic degree. The term thesis is also used to refer to the central claim of an essay or similar work. In fact, the terms “thesis” and “dissertation” are interchangeable. A thesis as well as a dissertation is a written discourse on the given subject. Although, there are 2 essential differences between a thesis and dissertation. A thesis means that you have to conduct original research. A dissertation implies that you have to synthesize the information collected and perhaps, include your thoughts on it. The second difference lies in the degree you obtain after completing these papers. A thesis allows getting the higher degree; a dissertation is more likely to be the smaller part of the first degree. It is not exactly on the extremes but very near.
When writing a thesis or dissertation, you will have to take into account the first difference we have presented. If you have to write a thesis, you should be aware of the fact that you are to put forward a hypothesis that is absolutely new, your thesis implies that original research is involved. Writing a dissertation requires your knowledge of the recent discoveries. It is also known as a statement made thru facts and research on the specific subject line. You have to draw absolutely new conclusions on the basis of what you have read and analyzed. In different institutions and countries, there is a different criterion to assign and examine thesis and dissertation. Similarly, thesis and dissertation are called with sometimes interchangeable names.
Thus, a thesis and dissertation are similar kinds of written papers, though differing a bit from each other. Dissertations and theses provide the opportunity to get certain grades. Theses or dissertations have to present the student’s knowledge of the certain subject area; both dissertations and theses have to provide innovations in certain areas of investigation. In some countries/universities, the word “thesis” or a cognate is used as part of a bachelor’s or master’s course, while “dissertation” is normally applied to a doctorate, while in others, the reverse is true. The length of thesis and dissertation is set by the individual departments and faculties based on subject therefore the length of thesis and dissertation varies. The length of thesis is around 100+ pages for dissertation around 300+ pages.
To sum it all up, we can say that a thesis is usually completed in a year since it is written in less number of pages than a dissertation. On the other hand, dissertation requires much more time than a thesis since it has a greater number of pages and it requires original research.
