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.
