Short Answer

In ANOVA, the F-test is the ratio of two sample variances. In the one-way ANOVA (completely randomised design), the variance used as the denominator of the ratio is the: $\begin{array}{|l|l|}\hline A.&\text { mean square for treatments.}\\\hline B.&\text {mean square for error. }\\\hline C.&\text {mean square for blocks. }\\\hline D.&\text {total sum of squares. }\\\hline \end{array}$
