The two types of Chi-square tests share the central idea of _____. A. comparing the population means to see if they vary from each other more than by chance B. testing the estimated degree of fit (proportion of variance accounted for) of one variable to the other variable C. testing how well the pattern of observed frequencies fits some expected pattern of frequencies D. comparing population variances, to see if they vary from each other more than by chance
