In the analysis of variance, the sum of the squared deviations between each block sample mean and the grand mean, multiplied by the number of observations made for each block, multiplied by the number of observations per cell (which may well equal 1) equals the blocks mean square.

Final Answer : False, Explanation :  In the analysis of variance, the description given mixes elements of calculating the sum of squares for blocks with the calculation of mean squares. The mean square for blocks is actually calculated by dividing the sum of squares for blocks by the degrees of freedom for blocks, not by multiplying deviations by the number of observations per cell.
