WebThe standard pair wise ranking method Pair wise ranking in which each item on a list is compared in a systematic way with each other provides such a method. An example of this is given in Table 1. To construct this table, each problem was compared in turn with each of the other problems. Thus “Lack of fertiliser” Webbased approach.
