C)sum of the deviations around the mean.
D)sum of the squared deviations around the mean.

Question

Quizplus · Accepted Answer

The definition of sample standard deviation involves taking the square root of the average of the squared deviations around the mean. This is because the squared deviations ensure that negative and positive deviations do not cancel each other out, and taking the average ensures that the measure is representative of the variability of the data. Therefore, the correct choice is B.
