"The political principle that anything can be proved by statistics arises from the practice of presenting only a selected sub-set of the data available." -- R. A. Fisher (1955)

". . . the higher statistics are only common sense reduced to numerical appreciation." -- Karl Pearson (Berkson, 1942, p. 325)
