Abstract:
In order to objectively retlect the grasp of students for knowledge of different difficulty,normal distribution of question numbers of different difficulty is required.From a mathematical view,the normal distribution function is built on a continuous space;it can not be directly applied to allocation algorithm of test questions.Therefore,the numerical algorithm of normal distribution function in continuous space is improved,so that the difficulty of the discretization of question difficulty and the difficul...
