chi-square test
Any of several methods used when the variables, especially the ∗dependent variables, to be analyzed are categorical rather than continuous (measured on an ∗interval or ∗ratio scale). These include the ∗chi-squared test, ∗log-linear analyses, ∗logistic regression, and ∗probit regression. [Source: Dictionary of Statistics & Methodology; Categorical Data Analysis]
