and here i was thinking i was being all progressive and modern by not making my biostats students work through all the calculations for anova by hand, but -- lo and behold! -- busy tosser has opined that the old-skool approach might actually be helpful. she's probably right;) so, let it never be said that i'm not willing to hand out additional work when it's asked for -- here you go:
a quick google search on "anova by hand" turned up the following worksheet:statisticshell.com/anovabyhand.pdf. the 'parent' site that it comes from -- statisticshell.com -- is a hoot. i've worked through the worksheet and it's actually quite good -- he walks you through one example (response to viagra, no less!) and then gives you a second problem to work on your own, followed by the answers to that one as well. i checked his results in R and get the same answers as he did, so -- if you're so inclined -- have at it!
let me know if it helps.

Awesome. This will be helpful for me. Thanks for the link! Also I am supposed to remind you that I would like to do MANOVA (basic assumptions, when to use it, an example, etc) but don't want to get bogged down into a complicated approach or some of the other stuff in the last chapter of G&E. I wouldn't mind reviewing some ANOVA if others are so inclined and I definitely cool with looking at experimental plots.
