Focus group session size?

• A. 50 participants.
• B. 4 to 12 participants.
• C. 1 to 2 participants.
• D. 20 to 30 participants.

Answer: (B)

Focus group discussions work best when there’s enough input from different people to surface a range of attitudes, but not so many that individuals can’t speak in depth. A group of four to twelve participants strikes that balance: it allows diverse views and interaction without the session becoming chaotic or dominated by a few voices. If there are fewer than four, you risk limited perspectives; more than twelve makes it hard for everyone to contribute and for the moderator to probe meaningfully. In practice, six to eight participants is common, but four to twelve is the standard range to plan for.
