Redo Exercise 1, replacing the college-major factor with the grouping variable you created in Computer Exercise 3 of Chapter 12 (from the number of math courses taken).

Data from exercise 1

Using college major and sex as your independent variables, perform a two-way ANOVA on the math background quiz. Request descriptive statistics. Use the cell means to explain your results. (Advanced exercise: Redo the two-way ANOVA without the psychology majors.)
