The document discusses key aspects of conducting interviews as a research method. It provides 3-4 main points about interviews:
1) Interviews are a flexible research tool that allow researchers to ask follow-up questions and explore responses in more depth than other methods like questionnaires.
2) When used properly, interviews can provide detailed information through conversation. However, they require a small sample size and are time-consuming.
3) Researchers must consider how to design interview schedules, including the appropriate number and types of questions and logical question order. Piloting the schedule is also important.
