A thesis is the final project for a graduate student's masters degree. Students pursing a masters degree typically perform research on a subject, using the research of others, and then provide an analysis of their discoveries. The thesis is similar to a large research paper that is done during college and demonstrates the student's ability to think critically and analyze information.
For students pursuing a doctoral degree, the dissertation is the final project. A dissertation differs from a masters thesis in that the student is expected to build upon the research of others to come up with a new hypothesis that will further the body of knowledge on a subject. Dissertations are generally much longer in length than a thesis. A masters thesis may be over 100 pages in length but a dissertation could easily be double or triple that.
