This document outlines the key concepts from Chapter 2 of the textbook "Asking and Answering Sociological Questions". It discusses how sociology differs from natural sciences in its study of human subjects. The research process in sociology involves 8 stages: defining problems, reviewing evidence, formulating hypotheses, designing studies, collecting data, interpreting results, reporting findings, and repeating the process. Sociologists explore factual, comparative, developmental, and theoretical questions using methods like ethnography, surveys, experiments, and comparative research.
