摘要
以某批替代物回收率数据为例,介绍如何用数据进行统计分析,利用格拉布斯检验法剔除离群值,并将检测数据绘制替代物回收率控制图,帮助发现检测过程的异常情况,从而对土壤半挥发性有机物检测实行质量控制,保证检测结果的准确、可靠。
Based on a batch of the recovery rate data of surrogates,the article introduces how to perform statistical analysis on the data through the use of Grubbs test to eliminate outliers,and draws the quality control chart of recovery.The use of quality control chart can help to detect abnormal factors in the detection process in time,in order to achieve quality control in detection of semivolatile organic compounds in soil and ensure the accuracy and reliability of detection results.
