I am trying to learn more about the statistics which is needed in day-to-day programming jobs like distribution, percentiles, window rates, deltas, etc. I never paid much attention to math and stats classes in college but I feel that was a mistake. :) Knowing all this seems especially useful when studying how the new service you deployed is behaving by monitoring a bunch of key metrics and deriving numbers (distributions, etc.) on top of them.

Does anyone have good suggestions of comprehensive resources (books, online tutorials, etc.) to learn more about statistics specifically useful in programming?
