What is the proper way to apply the multiple comparison test? [PDF]

open access: yesKorean Journal of Anesthesiology, 2018
Multiple comparisons tests (MCTs) are performed several times on the mean of experimental conditions. When the null hypothesis is rejected in a validation, MCTs are performed when certain experimental conditions have a statistically significant mean ...
