For the scenario below, determine which which one of the group threats to internal validity (selection or regression to the mean) is of most concern and provide one way to control for the threat. During the fall semester a study was conducted to determine if differences in performance and attitude exist for students enrolled in an on-line course in college level mathematics and a traditional on-campus delivery of the same college level mathematics course. Students self-selected the course that they were enrolled in and students were enrolled in one and only one of the courses.
