Dividing the sum of squares (SS) by the degrees of freedom (df) to calculate sample variance is an unbiased estimator, meaning it accurately estimates the population variance on average. However, this method does not guarantee minimum variance among all unbiased estimators, which means there could be other estimators that provide estimates with less variability around the population variance.
