A focus group is a group interview involving a small number of demographically similar people in which their reactions to specific researcher-posed questions are studied. Focus groups are used in market research and studies of people's political views. The idea is for the researcher to learn about the participants' reactions. If group members are representative of a larger population, those reactions can be expected to reflect the views of that larger population.[1][2][3] Thus focus groups constitute a research method that researchers organize for the purpose of collecting qualitative data, through interactive and directed discussions.[4]
The technique is used by a wide variety of professionals including sociologists, psychologists, and researchers in communication studies, education, political science, and public health.
