WebRank skewness is a new idea of measuring the coefficient of skewness and in this paper, we have suggested an alternative form to measure the amount of the coefficient of skewness, based on this new idea we have termed it as “Rank Skewness”. This new approach may play an important role to overcome the problem that we have explained earlier.
