WebbThe test statistic is a chi-square random variable (Χ 2) defined by the following equation. Χ 2 = Σ [ (O r,c - E r,c) 2 / E r,c ] where O r,c is the observed frequency count in population r for level c of the categorical variable, and E r,c is the expected frequency count in population r for level c of the categorical variable.
