WebApr 2, 2024 · A different test, called the test for homogeneity, can be used to draw a conclusion about whether two populations have the same distribution. To calculate the test statistic for a test for homogeneity, follow the same procedure as with the test of independence. The expected value for each cell needs to be at least five in order for you … WebFor chi-square tests based on two-way tables (both the test of independence and the test of homogeneity), the degrees of freedom are (r − 1)(c − 1), where r is the number of rows and c is the number of columns in the two-way table (not counting row and column totals). In this case, the degrees of freedom are (3 − 1)(2 − 1) = 2.
