Julia Evans shares some good resources for developers interested in statistics:
even more links
a paper someone said was good (by Efron): Bootstrap Methods: another look at the jackknife
this blog post has an overview of different nonparametric tests
this podcast with Philip Guo and John DeNero where they talk about teaching stats to programmers
openintro has free some statistics books
There are a lot of good links in Julia’s post. I should also mention that Andrew Gelman and Deborah Nolan have a new book coming out in July. Gelman’s Bayesian approach suits me well, so I’m pre-ordering the book.
