Dr. Dingo wants to see what individual differences (academic motivation, high school grade point average and academic integration) influence college students' first-year grade point average (GPA). She runs a multiple regression for which she finds that academic motivation (b = 5.26, p = .02) and high school GPA (b = 1.02, p = .005) are related to college GPA, but academic integration is not (b = .035, p =.48). In this example, what is/are the criterion variable(s)?

a. academic motivation and high school GPA

b. academic motivation, high school GPA and academic integration

c. college GPA

d. college students
