The expression S(X_i - $\bar { X }$) involves subtracting the mean ($\bar { X }$) from each score and adding up the deviations. This is effectively calculating the sum of the deviations from the mean, which is a common measure of variability in a distribution. Therefore, the correct choice is to subtract the mean from each score and add up the deviations (option D).
