Question

An instructor in a statistics class wants to evaluate the effectiveness of three teaching assistants using different instructional methods (1: small group work, 2: lecture, and 3: individual work with TA help). For one class session, the students are equally and randomly assigned into one of the three groups, each of which receives a lecture on “ANOVA” from one of the teaching assistants. At the next meeting of the class, the students are given a quiz on the material. To further control for students' difference, she recorded students' statistical aptitude measured at the beginning of the semester. The results of students' quiz score, their TA group, and their initial statistical aptitude are saved in “3 TA.”
