Suppose that a sample of 10 observations has a standard deviation of 3.Then the sum of the squared deviations from the sample mean is 30.

Question

Quizplus · Accepted Answer

The sum of the squared deviations from the sample mean is calculated using the formula $SS = (n-1)s^2$, where $n$ is the number of observations and $s$ is the sample standard deviation. For this example, $SS = (10-1) \times 3^2 = 9 \times 9 = 81$.
