This test is a special form of analysis called a non-parametric test, so the structure of it will look a little bit different from what we have done so far. However, the logic of hypothesis testing remains unchanged. The purpose of chi-square is to understand the frequency distribution of a single categorical variable or find a relation between two categorical variables, which is a frequently very useful way to look at our data.
