An Analysis of Variance Differs from a T Test for Independent

An analysis of variance differs from a t test for independent means in that an analysis of variance

A) is usually used to compare two groups,while a t test for independent means can be used to compare two or more groups.
B) can be used to compare three or more groups,while a t test for independent means cannot be used to compare more than two groups.
C) is conducted before the experiment,while a t test for independent means is conducted after the experiment.
D) includes computation of group variances as part of the analysis,while a t test does not include these computations.
