Association Between Two Categorical Variables: Contingency Analysis with Chi Square



Categorical variables, including nominal and ordinal variables, are described by tabulating their frequencies or probability. If two categorical variables are associated, the frequencies of values of one will depend on the frequencies of values of the other. Chi square tests the hypothesized association between two categorical variables, and contingency analysis quantifies their association.
