Performing an ANOVA test of three or more numeric columns’ means

An analysis of variance (ANOVA) test indicates whether the means of three or more numeric columns appear to differ from each other. It is a generalization of the unpaired t-test, which applies only to two groups.

To perform an ANOVA test:

1. In the Summary view, use the confidence slider to choose a desired confidence level
2. Command-click three or more numeric columns of interest on the left
3. Click the button labeled "t-test" below the Covariate view
4. The result of the ANOVA test will appear in the Bottom Line
