Grubbs Outlier Test

Introduction：

If calculated G > critical value, the data point can be rejected. The Grubbs outlier test tool is used to identify abnormal deviation data in repeated material test results. In tensile, hardness, and bending batch tests, individual outlier data often affects final average results. This calculator computes the Grubbs statistic value to assist engineers in scientifically judging whether suspicious data can be eliminated, ensuring test accuracy and report compliance with laboratory data processing specifications.
