3. Select weight and click Y, Response.

4. Select age and click X, Factor.

5. Click OK.

Figure 6.18 Example of Means Comparisons Report for All Pairs, Tukey HSD 

In Figure 6.18, the Tukey-Kramer HSD Threshold matrix shows the actual absolute difference in the means minus the HSD. This value represents the difference that would be significant. Pairs with a positive value are significantly different. The q* (appearing above the HSD Threshold Matrix table) is the quantile that is used to scale the HSDs. It has a computational role comparable to a Student’s t.
