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:
- In the Summary view, use the confidence slider to choose a
desired confidence level
- Choose the numeric column of interest on the left
- Choose the category column of interest in the Covariate table
- Click the button labeled t-test below the Covariate view
- 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.)
