This document outlines a hierarchical set of research questions to help identify large categories of issues in surveys and more specific questions within each category. It discusses how determining if a proposed question fits the purpose of the intended survey can help eliminate unnecessary questions, as the length of a survey's questionnaire impacts its success. Finally, it defines the target population as that which is studied in a survey, with the typical unit of analysis being people but also possibly objects, organizations, etc. Data is collected from individual units of analysis to describe and summarize the overall population.
