this article along. The story is super interesting, and might be relevant for those of you teaching statistics! (I tried to look up how they got all the formulas, but it ended up giving me a headache, because each link just led me to more formulas. Next summer, I really need to pick up a good book on statistics.)
Have a look at http://www.rsscse.org.uk/ts/gtb/contents.html

Sweet! Thanks for the link! That discussion is super clear/broken down; now I totally understand the formula.
ReplyDelete(The variance calculation formula still trips me up, but I think I'll need to revisit a bunch of more fundamental ideas of statistics before I can figure that one out.) :)
Math blogosphere to the rescue!
