RESEARCH BRAINTEASER
Please comment on the following statement:

You have been given a school research assignment that asks that you gather qualitative data to assist the school’s cafeteria in planning upcoming menus. Most of your classmates are just going around campus asking people their opinions on menu ideas. You realize that to be of service to the cafeteria (and your growling stomach) you need to better understand what makes people run to or run away from the school’s cafeteria. You decide to put together a focus group of students and staff members.

Question

Why is a focus group a good qualitative approach for this assignment?
