Calculating the variance (s²) involves ______ deviations because______. A) squaring; the sum of unsquared deviations is equal to 0 B) multiplying; samples are smaller than populations C) subtracting; deviations are always positive D) dividing; distributions are sometimes skewed (asymmetric)

Question

Quizplus · Accepted Answer

Calculating variance involves squaring deviations from the mean. Sum of unsquared deviations will not give the correct measure of dispersion. Therefore, variance is calculated by finding the sum of squared deviations from the mean, divided by the sample size.
