The chair of a local community college is interested in three things: 1) Whether or not there are differences in performance in different sections of intro psychology (9am class, 5pm class, and online class), 2) Whether or not performance changes over the course of the semester (Exam 1, Exam 2, and Final Exam), and 3) Whether or not there is an interaction between class section and exam. To help answer these questions, you will conduct a two-way ANOVA including both of these variables in the analysis. The data set includes exam scores for the three classes over the three exams. III. What is the dependent variable of this experiment? (1 point)
