Hi Kim,

Thank you for contacting us.

Multiple comparisons tests are used in penalty analysis to test the difference between means. Several methods are available, grouped into two categories:
multiple pairwise comparisons (ex. Tukey, Fisher, etc) and multiple comparisons with a control, the latter being here the JAR category.

To find these options, you need to open the dialog box of Penalty analysis and then go to the sub-tab outputs.

The corresponding results are displayed in the table “Penalty table” of the output. Last, the summary charts allow to quickly identify the JAR dimensions for which the differences between the JAR category and the 2 non-JAR categories (“Not enough”, “Too much”) are significantly different: when the difference is significant, the bars are displayed in red color, whereas they are displayed in green color when the difference is not significant. The bars are displayed in grey when the size of a group is lower than the select threshold (see the Options tab of the dialog box).

Regards,
Thalia
