Step 1

The chi-square is a non-parametric test which is used for comparing the categorical variables. Chi-square test is used to test whether there is relation between two-categorical variables or not in the study. It is a statistical method that tests whether at each level of the categorical variable the observed frequencies are similar to the expected frequencies or not. The test involves only two factors that can have any number of levels.

Step 2

It is clear that, chi-square test is used only when the data is categorical but not numerical data (interval, ratio). This shows that the statement is false.

Result: Option B. False
