Unfortunately, all my stats books are in my office, and I'm not. I don't have anyone book that has everything. I just don't know if such a thing exists. I have three stats books that together seem to cover all the basics. Oh, wait, just spotted one on the bookshelf here...that explains why I couldn't find it at the office the other day when trying to knock some sense into a stubborn post-doc

This one doesn't really cover basic stats, but is really handy when designing experiments. Hicks, CR. Fundamental Concepts in the Design of Experiments, 4th ed. Saunders College Publishing, New York, 1993. For simple stats like chi-squared, I have one that's statistics for behavioral sciences (not the exact title)...it's great, written very easy to read (because I guess statisticians think psychology majors can't do math...they could be right). The third one goes into greater detail on all the types of t-tests, variance, confidence intervals, etc.
What I have never managed to get my hands on is something that just lists all those different things in one book. My PhD mentor used to have a great text, long out of print, well-worn, and the disappearance of which would certainly be punishable by death. It had an assortment of standard parametric stats along with some nonparametric stats and easy to follow examples of how to calculate them (that text was written back when computers used punch cards, so people still hand-calculated that stuff).
Oh, do you need theory or just need to do a chi-squared test? I think Excel has a function for chi-squared analysis. I know it will do t-tests. Or do you just want a reference on hand that you don't need at the moment?
