We want to evaluate the intervention put into place last year where we eliminated Monday classes in college to see if this resulted in greater motivation, fewer illnesses/improved physical health, higher test scores, and reduced absenteeism. The results have been mixed so we are trying to improve this intervention. What type of sampling would it be if I asked a group of students at UC, a group of students at XU, and a group of students at Cincinnati State and compare differences across the groups?
