Which of the following would be an example of a design that examines the effects gender and school type (i.e. ,elementary,middle,or high school) on a scale of student attitudes toward learning?

A) 2 × 2 ANOVA
B) 3 × 3 ANOVA
C) 2 × 3 ANOVA
D) simple ANOVA

A 2 × 3 ANOVA would allow for examining the effects of both gender (2 levels) and school type (3 levels) on the scale of student attitudes toward learning. This design would allow for testing the main effects of each factor (i.e., the effect of gender and the effect of school type), as well as the interaction between these factors (i.e., whether the effect of gender differs depending on school type or vice versa). The 2 × 2 ANOVA would only allow for examining two levels of one factor and two levels of another factor, which would not allow for the examination of school type. The 3 × 3 ANOVA would allow for examining three levels of each factor, but would not be necessary if only two levels of one factor (gender) and three levels of another factor (school type) are of interest. A simple ANOVA refers to a one-way ANOVA with only one group factor, which is not suitable for examining the effects of both gender and school type.
