A major advantage of a two-factor analysis of variance over a one-factor analysis of variance is that
A) power is often increased
B) the denominator of the F-test is increased
C) interaction between factors can be identified
D) both a and c

Question

Quizplus · Accepted Answer

Two-factor analysis of variance can identify interaction effects between factors, which is not possible with a one-factor analysis of variance. Additionally, the inclusion of a second factor can often increase the power of the statistical test.
