As of the beginning of 2003, there is a much better way to fix that problem, and this page now (in displayed math, as opposed to symbols embedded in lines of text) takes advantage of that advance. Michael Hardy 01:14 Feb 9, 2003 (UTC)
Should we put an index n on our sample variance S2? AxelBoldt 07:58 Feb 9, 2003 (UTC)
Now I've done that. There are times when that matters; those are when the dependence on the sample-size n is important, especially when a limit as n approaches infinity is to be mentioned. Perhaps this article is not such an occasion, especially considering that Student's distribution is most important when n is small. But I've already put the subscript on the sample mean, so consistency makes it preferable to put it on the sample variance too. And it might also not hurt to mention the limiting distribution as the number of degrees of freedom grows. Michael Hardy 21:29 Feb 9, 2003 (UTC)
