To calculate SS (sum of squared deviations), we need to first find the mean of the scores:
Mean = (1+1+4+0)/4 = 1.5
Then, we calculate the difference between each score and the mean, square it and sum up the results:
(1-1.5)^2 + (1-1.5)^2 + (4-1.5)^2 + (0-1.5)^2 = 0.25 + 0.25 + 4.25 + 2.25 = 7
Therefore, SS = 7, and the correct answer is C)9.
