Abstract
Small sample difference ratio statistical procedures for testing goodness of fit to a uniform distribution of n observations in c categories and testing the independence of n observations in the cells of an r x c contingency table are described. The procedures make use of a D statistic ranging from a minimum value equal to or close to 0 to a maximum value of I. Larger values of D indicate greater deviations of the observed frequencies from a specified theoretical frequency distribution. Programs for computing the D values and for generating discrete and right-tail probabilities associated with various values of the D statistic are discussed; probability tables for determining the significance of D are provided.
