Chi-Square Goodness-of-Fit Test Critical Value Approach Assumptions 1. All expected frequencies are 1 or greater 2. At most 20% of the expected frequencies are less than 5.... 12/04/2007 · For chi-squared test for goodness of fit the expected count is found by multiplying the proportion of the distribution for each category times the sample size. For example, if your sample size is 10 with 5 categories that are equally distributed, your proportion is 20%. To find the expected count, multiply 20% and 10 to get 2. This can be checked by multiplying the number of categories by the
