Importance of a moderator

This Youtube video shows the importance of a moderator in a focus group interview. This guy is not ready for this interview at all. He does not know the medical terms or background of the product even thought it was a focus group interview about a technology being used in health care industry. Also he embarrassed a participant. This could make participants express their opinion passively. As professor Jennifer stressed in class, a moderator is a very important role in a focus group interview. A moderator should be fully prepared with background information about the subject matter of a focus group interview, and encourage participants so they can participate actively and come up with as many insights as they can.
