Dunnett’s multiple comparison test

a statistical method for assessing whether a control group is significantly different from each of several treatment groups. It is similar to the Dunn–Bonferroni procedure but not as stringent in that it does not require the significance level per comparison to be as small. The index of difference that is obtained from this test is called Dunnett’s t. [Charles W. Dunnett (1921–2007), Canadian statistician]
