The result is shown in the screenshot below. This is a typical Chi-Square test: if we assume that two variables are independent, then the values of the contingency table for these variables should be distributed uniformly.And then we check how far away from uniform the actual values are. This will make subsequent tables and charts look much nicer. All of the variables in your dataset appear in the list on the left side.
