A thesis is typically written as part of a master’s degree program, and is shorter and more focused than a dissertation. It is a specific, arguable, and debatable claim or argument that is supported by evidence and research. A thesis should make a unique contribution to the existing body of knowledge on a topic, and should be written in a clear and concise manner.

A dissertation, on the other hand, is typically written as part of a doctoral degree program, and is longer and more comprehensive than a thesis. It is an in-depth exploration of a specific topic, and should demonstrate the student’s ability to conduct original research and contribute to their field of study. A dissertation should be well-organized and well-written, and should include a thorough review of the literature, as well as a discussion of the implications of the research.

Overall, the main difference between a thesis and a dissertation is their purpose and focus. A thesis is a shorter and more focused document that makes a specific argument, while a dissertation is a longer and more comprehensive document that explores a topic in depth.
