| 摘 要： | 根据对长度为n的两个序列之间相关系数分布规律的理论探讨,得出相关系数的分布为正态分布且方差为1/n的结论,并用以找出大规模考试中成绩记录整场出错的考场.通过对考生成绩的相关性分析,根据相关系数即可迅速锁定可能出错考场,使得只需要抽检不到0.5%的考场,即可基本上找出全部整场出错的考场,从而提高了校对审核的效率.

| Abstract: | With theoretical probes to the distribution law of correlation coefficients between two n-length sequences,this paper concludes the normal distribution and with a variance of 1/n,aiming to indicate the examination rooms with overall scorekeeping mistakes which commonly occur in large-scale tests.Based on the correlation analyses of examination results,the coefficients can be used to point out almost all examination rooms with such mistakes by sampling the data of just less than 0.5 per cent rooms,which can raise the efficiency of error check dramatically. |
