Answer

Brief Explanations:

The Chi - square test is used to test the independence of two categorical (nominal or ordinal - level) variables. Nominal variables are unordered categories and ordinal variables are ordered categories. Interval and ratio - level variables are more appropriate for other types of statistical tests like t - tests or ANOVA when dealing with means.

Answer:

nominal - or ordinal - level variables are independent
