To begin the analysis, from the menus choose:

Analyze
 Compare Means
  One-Way ANOVA...

step Select Score on training exam as the dependent variable.

step Select Sales training group as the factor variable.

step Click Post Hoc.

The Post Hoc tests are divided into two sets:

  • The first set assumes groups with equal variances.
  • The second set does not assume that the variances are equal. Because the Levene test has already established that the variances across training groups are significantly different, we select from this list.

step Select Tamhane's T2.

step Click Continue.

step Click OK in the One-Way ANOVA dialog box.
