This essay analyses students paper marks and gets the quality target on examination questions, for example, the number of persons in every make range, the highest mark, the lowest mark, the average mark, the ease degree and the distinguishing degree. It can also judge whether the result obeys the normal distribution and draw out the distribution diagram of marks , it does deeply data mining from teachers and gets the possibility of teachers disclosing questions or raising marks against discipline, This essay discusses in detail the mathematical model and significance of every target in test paper analyzing and with the concrete realizing of program design.
