Grubbs' test (Grubbs 1969 and Stefansky 1972) is used to detect a single outlier in a univariate data set that follows an approximately normal distribution. If you suspect more than one outlier may be present, it is recommended that you use either the Tietjen-Moore test or the generalized extreme studentized deviate test instead of the Grubbs' test.

Grubbs’ Test is a statistical test that can be used to identify the presence of outliers in a dataset.To use this test, a dataset should be approximately normally distributed and have at least 7 observations. Grubbs’ Test is a statistical test that can be used to identify the presence of one outlier in a dataset. To use this test, the dataset you’re analyzing should be approximately normally distributed and, ideally, should have at least 7 observations. Grubbs' test (Grubbs 1969 and Stefansky 1972) is used to detect a single outlier in a univariate data set that follows an approximately normal distribution.

Silent video illustrating how to identify outliers using both the Q and Grubbs tests, using Excel 2007. GraphPad QuickCalcs (Grubbs test) was used to determine statistical outliers, and a test was used to compare mean t insulin levels between high-fat (HF)– and low-fat (LF)–fed mice.
2, can be used to test significance of the two smallest observations. Grubbs test applicability is limited by the calculated critical values in the paper itself, but is very suitable for small sample sizes (3 -25 for statistics (1) and 4 -20 for statistics (2)). The method allows evaluation simultaneously of two possible outliers in one method run.
