When we don't have access to population variance, we get an estimate of the sample variance by [ Select ] ["dividing one from the sample size", "adding one to the sample size", "subtracting one from the sample size"] . This is known as [ Select ] ["unbiased sample variance", "corrected formula"] . This formula controls for some of the [ Select ] ["bias", "inflation"] and gets us closer to the actual population variance.
