摘要：
Results are obtained throwing light on the range of applicability of the normal theory distribution of the correlation ratio to cases where the normal theory conditions are not satisfied. The index of dispersion used to test the homogeneity of binomial series is treated as a special case. A procedure is suggested for dealing with the situation where the x2 distribution can no longer be applied owing to the smallness of the sample sizes.
