I want to learn statistics and data mining
phren0logy: If you are starting from scratch without a very strong math background, I'd recommend:1.) Head First Statistics -- Pretty good, but beware the section on Bayes Theorem which is a bit off. This is a quick and casual intro, but worthwhile. I used it to refresh me on my college stats course (which was a long time ago), and I like it. There's also Head First Data Analysis, which I haven't read but could be a reasonable companion. HF Data Analysis uses Excel and R.2.) Using R for Introductory Statistics (Verzani) -- Good explanations and exercises, and you will also learn R. This second point is actually pretty important, because it's a very valuable tool. Whereas the Head First Stats book walks though pretty simple problems that you work out in pencil, the Verzani book has many real-world data sets to explore that would be impractical to do by hand. That said, I think it's valuable to work things out in pencil with the first book before you move on to this one.After these books, Elements of Statistical Learning seems to be the current favorite.
