When an analysis of variance is performed on samples drawn from k populations, the mean square between treatments (MSTR) is A)SSTR/n_T B)SSTR/(n_T - 1) C)SSTR/k D)SSTR/(k - 1) E)None of these alternatives is correct.

Question

Quizplus · Accepted Answer

The mean square between treatments (MSTR) is calculated by dividing the sum of squares between treatments (SSTR) by the degrees of freedom (DF) between treatments, which is equal to k - 1. Therefore, MSTR = SSTR/(k - 1).
