Description:
<jats:p> This article presents a new graphical method for handling data of the “prefer A,” “prefer B,” or “no preference” type. One novel and attractive feature of this analysis (in contrast to other methods currently used) is that the “no preference” responses are included as such in the analysis in a natural way and are neither discarded nor divided between the “prefer A” and “prefer B” categories. This informative graphical analysis is illustrated by four examples. </jats:p>
