If the question seeks to find out the proof of sample variance being an unbiased estimator of population variance, then the answer is that there is no proof as . The unbiased estimator's expected value is equal to the true value of the parameter being estimated. This is the usual estimator of variance.

Since e¯s2=n−1nσ2, we can obtain an unbiased estimator of σ2 by multiplying ¯s2 by .

We have now shown that the sample variance is an unbiased estimator of the population variance. Since e¯s2=n−1nσ2, we can obtain an unbiased estimator of σ2 by multiplying ¯s2 by . In this proof i use the . In statistics, bias is an objective property of an estimator.
