Talk:Bias of Sample Variance

From ProofWiki
Jump to navigation Jump to search

Suggest replacing $\hat {\sigma^2}$ with $S_{n}^{2}$ to emphasize it is the formula for sample variance (which is a biased estimator of the population variance), rather than the unbiased estimator of the population variance which is usually denoted $\hat {\sigma^2}$ -- for example $\hat {\sigma^2}$ represents the unbiased estimator for population variance on Bessel's Correction, rather than the biased estimator formula for sample variance that is cited on this page.

Changed it to ${S_n}^2$ because it's better. --prime mover (talk) 12:20, 12 October 2023 (UTC)
