“Make everything simpler, but not simple” - Albert Einstein


A statistical significance test used for variables that have been organized into categories and presented in a crosstab or contingency table. A cross-tab displays the frequency distribution of the two or more variables crossed against each other. When you summarize two categorical variables in a cross-tab, your implicit interest is “Are the two variables related or independent?” Chi-Square is a statistical technique that can be applied to assess this very question.
