A new software module called bmtest has been created to help researchers in psychology and other fields compare two groups more accurately. This module introduces the Brunner–Munzel test, which is a better alternative to the commonly used Wilcoxon–Mann–Whitney test. The Brunner–Munzel test has fewer unrealistic assumptions and is more robust when these assumptions are not met. By making this test accessible through jamovi, researchers can improve their nonparametric statistical analysis.
