It has seldom been the case that the actual and Pythagorean pennant winners differed in wins by nine or more (corresponding generally to one standard deviation or more) and never by as much as 18 or more (two standard deviations or more). However, it is most prudent (as in the case of most medical research) to use the more rigorous standard: a z-score of 2.0 or more corresponding to a 95-percent-plus confidence level before concluding that the difference in records was not due entirely to luck.
