本文通过对测试员的评分数据的分析,运用数理统计工具,研究建立普通话水平测试评分的误差的数学模型,就出现的主要现象进行理论分析,并将结果与实验数据进行对比。本文主要就测试的评分误差的对评分质量的影响从以下几个方面做一些探讨:(1)评分数据的标准差的意义;(2)考生程度不同对评分数据的标准差的影响;(3)标准差对考生成绩的评定的影响;(4)标准差对复审的影响;(5)测试员的评分能力评价。
In this paper, by analyzing the score data of the testers and using the mathematical statistics tools, this paper studies the mathematical model of error in establishing the Mandarin level test scores, and makes a theoretical analysis on the main phenomena that appear and compares the results with the experimental data. The main content of this paper is to discuss the influence of the test score error on the quality of the score from the following aspects: (1) the significance of the standard deviation of the score data; (2) the influence of the different test scores on the standard deviation of the score data; (3) ) Standard deviation on the evaluation of candidates; (4) the impact of standard deviation on the review; (5) the evaluation of the testers’ ability to score.
