Paired rankings data comes to us in two situations. One situation is when pairs of subjects, say husbands and wives, are asked to rank a group of objects. Another situation is when subjects are asked to rank a group of same objects at two time points, say, before and aster the treatment. In this study, we show how biplot techniques can be applied to represent graphically such paired rankings.
