A dissertation thesis is essentially a compilation of research work that is done in the course of a masters’ study. Students are expected to pick a topic and work on it and submit it for approval to a board. Dissertation topic ideas are discussed and cross examined at first and then approved before one actually starts working on the thesis dissertation writing.
This is not the same as a book review or economics thesis; rather it shows the student has seen and considered other opinions and studies on the topic and offers various perspectives on the chosen topic.
The difference between a thesis and dissertation is that a thesis is the compiled results of the research conducted for a degree while a dissertation is an original work of study published to be awarded a Ph. D or a doctoral degree. Dissertation vs. thesis essentially emphasizes that a dissertation should be well defended by the candidate.
