对实验室间比对结果分析的统计方法进行了探讨。比较了常用的统计方法——稳健统计法和经典统计法的计算过程，对几次实验室间的比对结果分别用这两种统计方法进行了分析，同时结合格拉布斯检验法对离群值进行判断，从而探讨了两种统计方法的适用范围。认为当比对数据较多时，可采用稳健统计法给出严格的评价结论；当比对数据较少时，应先利用格拉布斯检验法对离群值进行剔除，同时要考虑方法标准或产品标准规定的允许误差，然后对余下的数据用经典统计法进行分析和评价。

It is necessary to choose an appropriate statistical method to analyze the results of the inter-laboratory comparisons. In this article, it is compared firstly that the process of calculation of the two sorts of common statistical methods: robust statistics and classical statistics, then the writers analyze the results of some inter-laboratory comparisons adopting this two sorts of statistical method respectively, using Grubbs test to judge the outlier, and the proper applying range of this two statistical methods is discussed: when there is much more data in comparison, it is suitable to analyze the results adopting robust statistics; at that time the data is limited, it is necessary to get rid of the outlier using Grubbs test method, paying attention to the maximum permitted error in the standards of the method or the product, after this, it is appropriate to analyze and appraise the remainder adopting classical statistics.
