Chi Square Test For Homogeneity Calculator. A different test, called the test for homogeneity, can be used to draw a conclusion about whether two populations have the same distribution. Let's start by trying to get a feel for how our data might look if we have two equal multinomial distributions.

The main difference to remember between the two is that the test for. Goodness of fit used to test whether a frequency distribution fits an expected distribution. Observations must be independent of each other (so, for example, no matched pairs) cell count must be 5 or above for each cell in a 2 x 2.
