How Grubbs' test works. The first step is to quantify how far the outlier is from the others. Calculate the ratio Z as the difference between the outlier and the mean divided by the SD. If Z is large, the value is far from the others. Note that you calculate the mean and SD from all values, including the outlier. Grubbs's test detects one outlier at a time. This outlier is expunged from the dataset and the test is iterated until no outliers are detected. However, multiple iterations change the probabilities of detection, and the test should not be used for sample sizes of six or fewer since it frequently tags most of the points as outliers.

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. Statistical significance was defined as <0.05.P Results Generation of Mice With Adipocyte-PRR Deficiency To confirm efficiency of PRR deletion in adipocytes, preadi-

Minitab uses Grubbs' test statistic to calculate the p-value, which is the probability of rejecting the null hypothesis when it is true. GraphPad QuickCalcs: t test calculator Performs unpaired t test , Weldh's t test (doesn' t assume equal variances) and paired t test . Calculates exact P value and 95% confidence interval. 2, can be used to test significance of the two smallest observations.

Purpose: Detection of Outliers The Tietjen-Moore test (Tietjen-Moore 1972) is used to detect multiple outliers in a univariate data set that follows an approximately normal distribution.The Tietjen-Moore test is a generalization of the Grubbs' test to the case of multiple outliers. If testing for a single outlier, the Tietjen-Moore test is equivalent to the Grubbs' test.

Description: The Grubbs test, also know as the maximum normalized residual test, can be used to test for outliers in a univariate data set.
