The exist ence of outliers reduces the quality of data to a great extent, and makes the corresponding results of data analysis significantly change more, which will lead to people’s inaccurate judgments. In this article, we discuss the characteristics and origin of outliers, and introduce some test methods of normal distribution sample: sample quantity method, Dixon test method, Grubbs test method and Nair test method. Finally through example comparison, we have found that the test effect is associated with significant level.
