mode = mode measurement that occurs most often Probably Mass Function = f (x) mode of a distribution means the the value that has a greatest probability (same as above, just rephrased) "Simpson's Paradox" = the number of times instances in a single observation does not say anything about the whole of observations -- for instance, player A can have a better Batting Average than player B every year of their career, but player b might have a higher career Batting Average.
