An instructor at a college is interested in investigating whether classroom group work learning activities impact student success in a Psychology 101 course. The instructor teaches two psychology 101 classes with one taking place from 11-12:15 on Mondays and Wednesdays, and another section taking place from 11-12:15 on Tuesdays and Thursdays. In the MW section, the instructor does not incorporate any group work learning activities throughout the semester. In the TTH section, the instructor regularly utilizes group work learning activities in the classroom. All other elements of the course are the same. At the end of the semester, the instructor contrasts overall grades on a 100 point scale. The instructor utilizes a t-test to determine whether the scores are significantly different between the two classes.
