Quizplus · Accepted Answer

The main difference between a nominal group and a focus group is not the number of participants, but rather the structure and purpose of the group. A nominal group is a technique for generating ideas or solving problems by brainstorming individually and then sharing ideas in a group setting, while a focus group is a research method that uses a small group of people to gather data and opinions about a specific topic or product. Focus groups typically involve 6-10 participants, while nominal groups can be larger or smaller depending on the purpose and context.
