A thesis is a statement or central idea that a writer puts forward in an academic paper, often as part of a larger argument. It serves as a guide for the reader, outlining the main point or claim that the author intends to support with evidence and analysis. Theses are commonly found in essays, research papers, and dissertations, and they help to clarify the focus of the work. In academic settings, a thesis can also refer to a comprehensive research project completed by students, particularly at the graduate level. This type of thesis, often associated with a Master's degree or Ph.D., involves original research and contributes new knowledge to a specific field of study. The process typically includes formulating a research question, conducting experiments or studies, and presenting findings in a formal document.
