摘要
比较了稳健统计法和误差系数法在水中苯系物实验室间比对结果中的应用,分别采用两种方法对比对结果进行了分析,探讨了两种统计方法的差异和适用范围。结果显示,两种方法对此次比对结果的分析结论基本一致,在实际应用中应跟据实验室间比对的目的和样品特点选择合适的统计方法。
Robust statistics and error coefficient method were compared in inter-laboratorycomparison on BTEX in water.Two meth-ods were used to analyze the testing results and the range of applications were discussed.Results showed that two methods basically came to the sameconclusion.Appropriate statistical methods should bechosen according to the purpose of inter-laboratory comparison and the sample characteristics.
