Monte Carlo simulations and the chi-square test of independence

Abstract

A Monte Carlo program for sampling 2 by 2 contingency tables from a user-specified population is discussed. Applications include computer-assisted instruction (CAI) of statistics, evaluation of actual vs nominal Type I error rates of the chi-square test of independence when expected frequencies are less than 10, and estimation of the power of the chi-square test. © 1977 Psychonomic Society, Inc.
