This document provides guidance on developing problem statements and research questions for quantitative, qualitative, and mixed methods studies. It discusses key elements to include such as: stating the problem clearly and within an educational context; ensuring questions can be empirically investigated; specifying variables and populations; using deductive or inductive logic as appropriate; and considering emergent vs. anticipated design approaches. The document also provides examples of well-formed hypotheses and research questions on topics like the effects of interventions, relationships between variables, and case study examinations of phenomena.
