Abstract

The paper presents the method of measuring the similarity and difference in the frequency distributions of one categorical variable for different levels of another variable. This method calculates the similarity and correlation between the rows of the contingency table. In this work, we use it for the analysis of associations of cognitive indicators. The proposed categorical data association analysis method can be used as an addition to the classical chi-square test.
