A population of N = 10 scores has a standard deviation of $\sigma$ = 2.What is the value of SS,the sum of the squared deviations,for this population?
A)40
B)20
C)4
D)2

Question

Quizplus · Accepted Answer

The sum of the squared deviations is equal to N times the variance. The variance is equal to the square of the standard deviation. Therefore, SS = N * F1F1F1S1F1F1F10^2 = 10 * 2^2 = 40.
