The Difference plot in the Matched Pairs report shows differences by means. In the Difference plot the mean difference is shown as the horizontal line. The 95% confidence interval is shown as dotted lines above and below the mean difference. If the confidence region includes zero, then the means are not significantly different at the 0.05 level. 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.
