  1. The rest of the table shows the results of multiple comparison of mean ranks to reveal whether each pair of groups differ from each other in a statistically significant way. Rejection of null hypothesis is highlighted in blue and red. The red color means that the quality of the signal after compression and reconstruction is better for the other group than it was assumed.
