Why the Minitab program does not present the Scheffé test (of multiple comparisons of means) after the ANOVA test ...
I have made a RM ANOVA and post it was looking for Scheffe test ....
Surprise! It's not possible! Why?
My doubt is the following
'it's possible to compare means of two independent groups without considering standard deviations" ?
Control Group: mean +- standard deviation 50 +- 10 mm
Experimental Group: mean +- standard deviation 100 +- 30 mm
I am very...
