What is the difference between Overall-type questions and People based-type questions, and why do I have to separate the two on my surveys?

Overall-type questions are course-based questions pertaining to the course. People based-type questions are faculty-based questions pertaining to each of the instructors. The two are separated to allow for the evaluation of multiple instructors on a course. Students will only answer Overall questions once on a survey, but if there are multiple instructors on a course, the system will assign the instructor-based questions to each individual instructor. This will play a major role in reports data access as well.
