The Khan academy lectures (and worked examples therein) are pretty awesome at showing you how to do relatively simple things like t-tests. Although I should add that I’ve taken stats in the past so it wasn’t completely new to me, YMMV. But since each lecture is all of 10 minutes long I don’t think the costs are too high.
