The Two-Sample t-test and the Influence of Outliers : - A simulation study on how the type I error rate is impacted by outliers of different magnitude.

The Two-Sample t-test and the Influence of Outliers : - A simulation study on how the type I error rate is impacted by outliers of different magnitude.

This study investigates how outliers of different magnitude impact the robustness of the twosample t-test. A simulation study approach is used to analyze the behavior of type I error rates when outliers are added to generated data. Outliers may distort parameter estimates such as the mean and varian...
