Groups must be mutually exclusive. Web in the test of homogeneity, we select random samples from each subgroup or population separately and collect data on a single categorical variable. The population proportions are nonhomogeneous. The variables must be categorical. The null hypothesis says that the distribution of the categorical variable is the same for each subgroup or population.

It is used to determine whether frequency counts are distributed identically across different populations. The population proportions are nonhomogeneous. The population proportions are nonhomogeneous.

The Null Hypothesis Says That The Distribution Of The Categorical Variable Is The Same For Each Subgroup Or Population.

It is used to determine whether frequency counts are distributed identically across different populations. Tests of independence involve using a contingency table of observed (data) values. The population proportions are homogeneous. To conduct a chi square test of homogeneity, you will need to have the following:
