Performing a t-test of a numeric column’s mean across two categories

A two-sample t-test indicates whether a numeric column’s mean appears to differ across two categories. It is equivalent to an ANOVA test, which is a generalization of the two-sample t-test to more than two categories.

To perform a two-sample t-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 a category column that takes two values in the Covariate table
  4. Click the button labeled t-test below the Covariate view
  5. The result of the two-sample t-test will appear in the Bottom Line
