This document discusses defining and selecting a research problem. It provides several criteria for selecting a good problem, including novelty, importance, interest to the researcher, and feasibility. A research problem refers to a difficulty a researcher wants to solve in a theoretical or practical context. A problem statement should clearly outline the problem in 1-2 sentences using the 5Ws (who, what, when, where, why). It should also address how the problem will be studied and tested. Characteristics of a good problem include being empirically testable and examining relationships between variables. Defining the problem sets the direction and goals of the study.
