摘要：
Samples from populations differing greatly from the normal give distributions of like the theoretical distributions in samples from a normal population. The values of r in actual samples from a normal population of high correlation seem to follow the theoretical distribution. The distribution of r in samples from coarsely grouped correlation tables seems essentially the same as the theoretical distribution of r in samples from a continuous population in which the value of [rho] is that obtained from the correlation table without applying Sheppard''s correction. This might be taken as indicating that Sheppard''s correction should be applied to the sample. It is better to avoid coarse grouping.
