| 摘 要： | 讨论了对高考作文评分进行监控的一种有效方法，建立了相应的统计模型。高考语文卷的作文分和知识题分具有群体相关，分布的分位数之间有线性关系，由样本得出此线性关系的参数的最小二乘估计。讨论了所得估计的大样本性质。证明估计量是渐近正态的。由此构造出对作文评分进行监控的EQQ控制图。

| Abstract: | Abstract It present a method for evaluation on justice in grading compositions ofenrollment exams and discuss its statistical model.We discovered the distributionsof grades of compositions and grades of other questions are similar in Chinese ex-ams.There is a linear correlation between qauntiles of two distribution fuctions.The MLE's of parameters of the linear correlation are asymptotic normal.Finallywe presented the EQQ Chart for evaluation on justice in grading compositions. |
