Final answer:
The ideal size for a focus group typically ranges from 6-8 participants, which allows for in-depth discussion and ensures that everyone has the opportunity to speak.
Step-by-step explanation:
A focus group is a qualitative research method that brings together a small number of people to discuss specific topics of interest in a guided discussion. The size of a focus group can influence the depth and quality of the discussions, making the selection of the appropriate number of participants crucial. While there is no one-size-fits-all number, conventional wisdom suggests that a focus group should consist of approximately 6-10 participants. This is because a smaller group allows for more detailed conversation and ensures that each participant has the opportunity to contribute meaningfully. Very large groups can suppress individual voices and reduce the opportunity for interaction.
In a mini-case study, the program director asked approximately six or seven people to participate in a focus group, which aligns with the idea that smaller focus groups can facilitate richer discussion, although in that particular case, there were mitigating factors that influenced the outcome negatively. To ensure that focus groups yield productive results, it is essential to consider not just the number, but also the composition of the group, the setting, and the facilitation methods used.
Therefore, in response to the student's question, the recommended size for a focus group should consist of 6-8 potential customers (Option 1), as this size is typically conducive to dynamic and manageable group discussions.
