In an analysis of variance where the total sample size for the experiment is n_T and the number of populations is k, the mean square due to error is A) SSE/(n_T - k). B) SSTR/(n_T - k). C) SSE/(k - 1). D) SSTR/k.

The mean square due to error is calculated as SSE/(n-k), where SSE is the sum of squares due to error and n is the total sample size. In this problem, n=n_T and k is the number of populations. Therefore, the correct formula is SSE/(n_T - k).
