Hajar, I am very familiar with the Tukey features of JMP software, which I've been using since 1997. I was not aware that Minitab supported Tukey's test for means' comparisons.
Thanks Charles Recchia for you suggestion and the help you are providing but I am not familiar with JMP. I am teaching students Minitab software so it will be difficult for me teach them all about JMP . However, I will contact you and ask for your help when I did not get any solution for what I am looking for.
