In addition to assessing whether each of your independent variables has an effect on the dependent variable, a factorial ANOVA also allows you to:
A) use multiple dependent measures in a single analysis.
B) control for a third variable that might be related to your dependent measure prior to
investigating the independent variable of interest.
C) determine whether the effects of one factor depend on the other factor.
D) partition out the variability due to individual differences and the variability due to
measurement error.
