Note that the 5% significance level applies to experiments, not to values. If you set alpha to 5% with the Grubbs test, then if the data are all Gaussian there is a 5% chance that any particular experiment will have an outlier. It doesnotmean that each value has a 5% chance of being ...
If the resulting test statistic g is greater than the critical value, the corresponding value can be regarded to be an outlier. An extract of the critical values is shown in the following table: n gcrit α=0.05 gcrit α=0.01 n gcrit α=0.05 gcrit α=0.01 n gcrit α=0.05 gcrit α...

or submit the standardized residuals to a Grubbs test to see if one or two values are abnormal. The classical Grubbs test can help identifying one outlier, while the double Grubbs test allows identifying two. It is not recommended to use these methods repeatedly on the same sample. However, ...
According to ISO 5725-2 (1994), measurement results obtained in an interlaboratory experiment are inspected for consistency by plotting Mandel’s h and k statistics and for outliers by application of the Grubbs test and the Cochran test. Critical values of these statistics for significance levels ...
