The Difference plot shows differences by means. In the Difference plot, note the following:

• The mean difference is shown as the horizontal line, with the 95% confidence interval above and below shown as dotted lines. If the confidence region includes zero, then the means are not significantly different at the 0.05 level. In this example, the difference is significant.

• If you add a reference frame, the mean of pairs is shown by the vertical line. For more information about a reference frame, see Matched Pairs Platform Options.

The Difference report shows the mean of each response, the difference of the means, and a confidence interval for the difference. The Difference report also shows the results of the paired t test.
