1. Know what is meant by the test for homegeneity. The test for Homogeneity is evalauting the equality of several populations of categorical data. The test The marginal homogeneity test / stuart-maxwell test tests the above null hypothesis against the following alternative hypothesis (H 1 or H a): H 1 : for some categories of the dependent variable, $\pi_j$ for the first paired group $ eq$ $\pi_j$ for the second paired group. The homogeneity test is a statistical test method, that checks if two (or more) datasets come from the same distribution or not.

If your data is normally distributed you can use Bartlett’s test instead of Levene’s. Testing homogeneity. Up till now, both for the 2×2 tables we looked at in Unit 9, and for the goodness of fit tests given above, we have assumed that we are dealing with a single sample or trial result.

We use Step 3: Assess the evidence.. We The goodness–of–fit test can be used to decide whether a population fits a given distribution, but it will not suffice to decide whether two populations follow the same unknown distribution. A different test, called the test for homogeneity, can be used to draw a conclusion about whether two populations have the same distribution.
