The distribution of the test statistic for analysis of variance is the:
A) normal distribution
B) Student t-distribution
C) F-distribution
D) binomial distribution
E) chi-square distribution

Question

Quizplus · Accepted Answer

The distribution of the test statistic for analysis of variance is the F-distribution. This is because the test statistic is calculated by dividing the mean square between groups by the mean square within groups, and this ratio follows an F-distribution under the null hypothesis of no group differences. Therefore, the correct choice is C.
