Quizplus · Accepted Answer

The sum of squared deviations (SS) is calculated by first finding the mean of the sample, then subtracting the mean from each value in the sample, squaring those differences, and finally summing them up. For the sample 2, 3, 4, 7, the mean is (2+3+4+7)/4 = 16/4 = 4. The squared deviations from the mean are (2-4)^2 + (3-4)^2 + (4-4)^2 + (7-4)^2 = 4 + 1 + 0 + 9 = 14.
