The fourth method of data collection involves the use of focus groups. A focusgroup is a situation where a focus group moderator keeps a small and homogeneous group (of 6–12 people) focused on the discussion of a research topicor issue. Focus group sessions generally last between 1 and 3 hours and are recorded using audio and/or videotapes. A focus group should not be viewed as agroup interview because the emphasis is on small-group interaction and in-depth discussion among the participants about the issues being studied. Focus groupsare especially useful for exploring ideas and obtaining in-depth information abouthow people think about an issue. The strengths and weaknesses of focus groupsas a method of data collection are provided in Table 2.6.
