On set-function representations of the n-grade evaluation values.

Abstract

On the analyses n-grade evaluation values, we usually use the mean values with examinee. The mean values often hide the rank differences of criterion among the subjects. The set-function representations of the evaluation values are depended on the rank information and keep the rank differences of each subject response. In this paper, we try to show the method and indexes of the number-based set-functions and the Shapley value interpretations.
