Standard deviation - Wikipedia
Population standard deviation: Sample standard deviation: Population variance: Sample variance: Behavior of Sample Variances: Sample variances target the value of the population variance (ie: the mean of the sample variances is the population variance) The distribution of sample variances tends to be a distribution skewed to the right.
