Sample Variance Vs Variance Of Sample Mean. The sample variance is an estimator for the population variance. Our result indicates that as the sample size n increases, the variance of the sample mean decreases.
Population variance refers to the value of variance that is calculated from population data, and sample variance is the variance calculated from sample .
Our result indicates that as the sample size n increases, the variance of the sample mean decreases. Population variance refers to the value of variance that is calculated from population data, and sample variance is the variance calculated from sample . When you're doing the population variance, you would take each data point in the population, find the distance between that and the normal population mean, take . Normally, however, only a subset is .
