Names of vegetables and fruit into piles (see bankruptcy three for details). From the ensuing judged similarity facts we played a multidimensional scaling research to acquire a spatial illustration. determine 2.1 exhibits the implications. during this photo, goods that have been judged related are on the subject of one another whereas goods judged as varied are extra aside.
