You want to determine the optimal tutor-to-student ratio. Students seeking tutoring will be randomly assigned to one of two groups:
Group 1 will involve each tutor working with only one student, and in Group 2, each tutor will work with two 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.
