You want to determine the optimal tutor-to-student ratio. Students seeking tutoring will be randomly assigned to one of three groups:
Group 1 will involve each tutor working with only one student; in Group 2, each tutor will work with two students; and in Group 3, each tutor will work with five students. At the end of the term, students will be asked to complete the Tutor Satisfaction Survey, which renders a score from 0 to 100, and the number of months that the tutor has been providing tutoring service (as the covariate).
