My Statistics Primer

Is still pretty good, I think. You can find it on my website (the link at the top of the blog) or here:

Part 1: Samples

Part 2: Probability

Part 3: Sample Statistics

Part 4: Sampling Distributions

Part 5: Constructing a Confidence Interval for the Sample Proportion

Part 6: Wrapping it All Up

It needs more parts, though. Stuff on correlation and friends.
