This document provides guidance on choosing a research question by outlining four key steps: 1) Choose a broad thematic area of interest, 2) Conduct a literature review on the topic, 3) Identify the units of analysis or targets of the research, and 4) Identify specific concepts, constructs, or variables that will be analyzed within the chosen units. Examples are provided for each step to illustrate how to narrow a topic into an answerable research question that builds on existing knowledge and identifies what or who will be studied and which of their characteristics or behaviors.
