Multiple Y Columns
You can have more than two responses. If the number of responses is odd, all possible pairs are analyzed. The following table shows an example for three responses.
Y1 by Y2
Y1 by Y3
Y2 by Y3
If the number of responses is even, the Matched Pairs platform asks whether you want to do all possible pairs. If you do not do all possible pairs, adjacent responses are analyzed as a pair. The following table shows the arrangement of analyses for four responses.
Y1 by Y2
Y3 by Y4
