Abstract
Suppose we have a preference polygon expressed by an inspector who has used the method of paired comparisons. The number of circular triads that the polygon contains is often used for data analysis. However, we found it useful to consider not only circular triads but also circular tetrads to data analysis. In this paper, we investigate the method of counting the number of circular tetrads.Subsequently, we obtain the probability distribution of the number of tetrads in the preference polygon when the inspector makes the judgment at random.
