Sociologists follow several steps when deciding what to research:
1. They choose a topic influenced by their interests, current debates, and practical issues like time and resources.
2. They read previous research on the topic.
3. They form a hypothesis or research question to focus the study.
4. They prepare a research design which may involve collecting primary or secondary data using various methods like surveys, observation, existing statistics, and documents. Sample selection is important to make generalizations about the overall population.
