This chapter considers different types and forms of interviewing, including focus groups, and how they should be conducted. Interviews are a popular method of data collection in political research. They share similarities with surveys, but these similarities relate mostly to structured interviews. The chapter focuses on semi-structured interviews, including focus groups, the emphasis of which is to get the interviewee to open up and discuss something of relevance to the research question. After describing the different types and forms of interview, the chapter explains how interview data can be used to confirm or disconfirm a hypothesis or argument. It also shows how to plan and carry out an interview and how the type and wording of questions, as well as the order in which they are asked, affect the responses you get. Finally, it examines the interviewing skills that will ensure a more successful outcome to an interview.
This chapter focuses on the basic principles of research design. It first considers different types of research design, including experimental designs, cross-sectional and longitudinal designs, comparative designs, and historical research designs. It also discusses two types of research validity: internal validity and external validity. The chapter proceeds by describing various methods of data collection and the sort of data or evidence each provides, including questionnaires and surveys, interviewing and focus groups, ethnographic research, and discourse/content analysis. Finally, it examines six issues that must be taken into account to ensure ethical research: voluntary participation, informed consent, privacy, harm, exploitation, and consequences for future research.
