The value of SS (Sum of Squares) can be calculated regardless of whether the data represents a sample or a population. SS = Σ(X - M)^2, where X is each score and M is the mean of the scores. The mean (M) of the scores 0, 1, 4, 5 is (0+1+4+5)/4 = 2.5. SS = (0-2.5)^2 + (1-2.5)^2 + (4-2.5)^2 + (5-2.5)^2 = 6.25 + 2.25 + 2.25 + 6.25 = 17.
