摘要：

由目前普遍使用的分析化学教材中与离群值相关的内容出发，对其进行对比和分析，说明数据离群值检验的意义和重要性。对几种常见的离群值判定方法进行了列举和比较，并对已确认为异常值的数据的处理方法也进行了对比和讨论。各种检验和处理方法各有其优势和劣势，根据实际情况选择不同方法或多种方法配合使用，能够更好地实现对离群值的检验和处理。

关键词: 离群值, 离群值检验方法, 离群值处理

Abstract:

This paper compares and analyzes outliers related contents in analytical chemistry textbooks which are widely used nowadays, and explains the significance of the detection of outliers. Several common methods for testing outliers are introduced and compared, and the data treatment methods of dealing with confirmed outliers are also compared and discussed. All kinds of methods have their own advantages and disadvantages, thus we should choose different methods or a variety of methods, in accordance with the actual situation, to achieve better detection and treatment of outliers.

Key words: Outlier, Test of methods of outliers, Treatment of outliers
