A standalone Windows program that calculates the chi-square statistic for 2x2 to 10x10 contingency tables. Also calculates the contingency coefficient, phi, and kappa statistics. The chi-square test is used to compare the distributions of two independent samples. It is used with data in the form of frequencies. It is a nonparametric procedure that makes no assumptions about distribution shapes, variances, or levels of measurement.
