In addition to assessing whether each independent variable has an effect on the dependent variable, a factorial ANOVA also allows one to:
A) use multiple dependent measures in a single analysis.
B) control for a third variable that might be related to the 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.
