# Performing an ANOVA test of a numeric column’s mean across values of another column

An analysis of variance (ANOVA) test indicates whether the mean of a numeric column appears to vary across category values or groupings.

To perform an ANOVA test:

1. In the Summary view, use the confidence slider to choose a desired confidence level
2. Choose the numeric column of interest on the left
3. Choose the category column of interest in the Covariate table
4. Click the button labeled t-test below the Covariate view
5. The result of the ANOVA test will appear in the Bottom Line

If only two category values are present, a two-sample t-test will be performed instead. (With two categories, two-sample t-tests are equivalent to ANOVA tests.)
