Talk:Sample mean and covariance

Often I have disagreed with the "too technical" tag, but here it's appropriate. This article should get reorganized. Michael Hardy (talk) 22:36, 28 September 2018 (UTC)

Completely agree. Rather than too technical, it is unnecessarily involved. The page should begin by discussing the sample mean of a scalar random variable. Txebixev (talk) 17:38, 2 September 2020 (UTC)
