Application of the broken line type nondimensionalization method in mathematical statistics

摘要

This paper introduces three nondimensionalization methods, applies these three methodsaccording to college grade comprehensive sort, describes the three methods in detail and finally makes a comparison of these three nondimensionalization methods. By exploring the application of nondimensionalization method in comprehensive evaluation of student achievement and comparing the advantage and disadvantage of traditional sort method and nondimensionalization sort method, this paper makes the briefly commentat the end and points out its development direction.
