摘　　要：基于统计分析方法,把实验结果作为综合评定实验成绩的一部分。利用统计分析软件(SPSS),采用标准偏差以及等距分组-样本均值与总体均值显著性分析2种方法分别对实验成绩进行评定分类。结果表明,2种方法对实验成绩的客观评定效果均较好,操作规范,避免了主观因素的干扰。与标准偏差方法相比,等距分组-均值显著性分析法更简单快捷,可以科学准确地评定实验结果,对实验课程成绩的客观评价具有重要的意义。On the basis of statistic analysis, the experimental result is evaluated as a part of the comprehensive assessment. Two evaluation methods, namely, the standard deviation and equidistant grouping for the significant analysis of sample mean and population mean with the help of SPSS software was used to evaluate the classify the experimental results. The results showed that both methods had merits of better effect for the objective evaluation of experimental results, standard operation, and avoiding the interference of subjective factors. Compared with the method of standard deviation, the method of equi- distant grouping for the significant analysis of mean was simpler and more efficient. The methods could be used to evaluate the experimental results scientifically and accurately, which had significant meaning for the objective evaluation of the results of the experimental course.
