摘要：
In an effort to end the controversy which has raged since 1941, Pearson, following Barnard, has differentiated between 3 distinct situations in which data may be classed in a 2 X 2 table. The 3 situations produce tables in which (a) both margins are fixed, (b) one is fixed and (c) neither is fixed. Corresponding to the first, the appropriate test is Fisher''s exact distribution. Corresponding to the others, Pearson suggests a compound probability consisting of the probability of the observed marginal totals multiplied by the probability as given by the exact distribution. In an appendix, there is given the normal approximation to the exact distribution.
