Many supervisors have appropriate and interesting topics available, and are often looking for suitable students to fill these projects and focus the topics. Enthusiastic supervisory attention is usually a feature of these projects. The objectives, questions or hypotheses to be answered. The research problem, when phrased, gives purpose to the intended work. Objectives are pithy statements of what is intended to be achieved, thereby answering the research problem.
Hypotheses come in pairs, the null and alternative hypotheses.
I favor using objectives and questions. Hypothesis-formation is popular, but often hypotheses can often end up sounding rather contrived and robotic. You should always be asking yourself questions about your own topic to refine it and check its feasibility. A summary of the existing research to provide a context for your own research. This is as revealed by a bibliography and brief literature review.
