Focus Group Discussion

A focus group discussion is a specific methodology in line with CEA in order to conduct an open discussion among a selected group to investigate the reactions that can be expected from a larger population.[1][2][3]

Quoting Wikipedia:[4]
A focus group is a small, but demographically diverse group of people and whose reactions are studied especially in market research or political analysis in guided or open discussions about a new product or something else to determine the reactions that can be expected from a larger population. It is a form of qualitative research consisting of interviews in which a group of people are asked about their perceptions, opinions, beliefs, and attitudes towards a product, service, concept, advertisement, idea, or packaging. Questions are asked in an interactive group setting where participants are free to talk with other group members. During this process, the researcher either takes notes or records the vital points he or she is getting from the group. Researchers should select members of the focus group carefully for effective and authoritative responses.
