Testing the statistical independence of two category columns

A test of statistical independence can indicate whether the values of two category columns are correlated. To perform an independence test:

1. In the Summary view, select one column on the left to include in the test
2. Use the confidence slider to choose the desired confidence level
3. Select the other column of interest in the covariate table on the right

"The Bottom Line" will then indicate whether a statistically significant dependence exists between the columns.

To view the p-value of the independence test, control-click the column heading of the covariate table and choose P-value.
