W01 Notes: Inference and hypothesis testing
... If you generate p-values for all 20,000 tests of difference in means, what should they look like? A p-value is "the probability of a result occurring by chance" Thus every value between 0 and 1 is, if your assumptions are correct, equally likely! You expect 10% of them to fall in the range 0-0.1, or ...
