Which of the following would be an example of a design that examines the effects of gender and SES (high SES and low SES) on a test of student achievement?

A) one-way ANOVA
B) 2 × 2 ANOVA
C) multivariate ANOVA
D) 3 × 2 ANOVA

A 2 × 2 ANOVA is used to examine the effects of two independent variables (in this case, gender and SES, each with two levels: male/female and high SES/low SES) on a dependent variable (student achievement). This design allows for the examination of both the main effects of each independent variable and their interaction effect on the dependent variable.
