摘　　要：试卷质量分析具有成熟的数学模型,但由于计算项目多样、过程繁琐,多数情况下需要借助统计软件完成分析过程。结合程序流程图,介绍了试卷质量分析数学模型的R语言实现,并以实例数据验证其有效性。结果表明,基于R语言的程序脚本可以快速获取多种基本描述性统计指标、正态性检验结果和难度、区分度、效度、信度等四度指标。R语言用于试卷质量分析可行、有效,相比其他大型商业统计软件,具有明显的便捷性。There exist recognized mathematical models for quality analysis of examination paper.However,the process of quality analysis in the most of cases needs to be completed with the help of statistical software,due to diverse items and cumbersome calculation process.By using program flowchart,this paper introduces the R implementation of these mathematical models,and verified its effectiveness based on case studies.The results indicates that R scripts could quickly obtain a variety of information,including basic descriptive statistics,normality test,and four degrees of difficulty, discrimination,validity and reliability.It's feasible,effective to employ R in quality analysis of examination paper,and compared with other commercial statistical software,it's more convenient.
