摘要： 在常用试题自动分配算法的基础上，提出一种基于正态分布的试题自动分发模型。在该模型中，试题空间被划分为不同难度等级的试题集，再将难度等级按正态分布。该模型具有结构简单、运行速度快、效率高、选题重点突出以及可行性好等特点，已经应用于主观编程题上机考试系统中。
关键词: 正态分布, 试题难度, 正态分布随机数, 离散化
Abstract: This paper issues a model of test assignment based on normal distribution, according to commonly used algorithms of automatic assignment. In this model, test space is divided into different difficulty levels of test set, then the difficulty levels are distributed according to the normal distribution. The model has a simple structure, fast, efficient, focused topics and feasibility of good features and has been applied to the subjective test examination on computer programming system.
Key words: normal distribution, item difficulty, normally distributed random numbers, discrete
