| 摘 要： | 目的：检验二个无关问题模型在学生作弊调查中的应用效率。方法：结合两个无关问题模型介绍了敏感问题的调查与统计处理技术（ＲＲＴ）的原理、实施步骤及计算方法。同时应用两个无关问题模型调查了某校两个班考试作弊情况，并作相应统计处理。结果：经分析发现，敏感问题在第二次调查时应答率下降（Ｐ＝０．０１），作弊率也有下降倾向，但Ｐ＞０．０５。不同性别作弊率则明显有差异，男生高于女生（Ｐ＝０．０２４７）。两个班作弊率没发现统计差异，总体作弊率较高。结论：调查结果说明用此法调查学生作弊情况是可行的。

Application of the Randomized Response Technique in Estimating the Proportion of cheating on Tests |

| Abstract: | Objective:To estimate the effect of two unrelated questions randomized response model in surveying proportion of cheating on test (PCOT).Methods:In this pape,two unrelated questions randomized response model of RRT was discussed and used in a certain college to estimate the PCOT among the students of two classes.Results:Response proportion of Sensitive questions was lower in the second survey(P=0.01).The PCOT was inclined to lower in the second,but no significant difference of statistics was found(P>0.05).The PCOT of male students was higher than femal(P=0.0247).The PCOT was different between two classes.The total PCOT was in high level.Conclusion:The results revealed that RRT can be used in survey of PCOT. |
