↗

To compute the sample variance using the divisor n-1, you calculate the sum of the squared deviations of each observation from the sample mean. Then, you divide this squared-deviation total by n-1, where n is the sample size.

Conditions: You have a sample of observations.; You are calculating the variance with divisor n-1.
