I'm trying to learn elementary statistics, but I cannot find a good book (or website) to start with. I tried 'Introductory Statistics with R' but it assumes you already understand basic statistics. Everything that I lookup on Amazon is a textbook and cost an arm and a leg, and I'd rather not shell out for something that I'm not sure about. So tell me, how did you learn statistics and what would you suggest to someone whose been programming for 10+ years but doesn't know what to do with a standard deviation.
