Question

To calculate the variance for a sample,SS is divided by df = n - 1.​

Quizplus · Accepted Answer

This is true. The formula for calculating the sample variance is:
s^2 = SS/(n-1)
where SS is the sum of squared deviations from the mean and n is the sample size. The denominator is n-1 because using n as the denominator would lead to a biased estimate of the population variance.
