The test is also similar to Nemenyi except that this time we use Dunnett Table. cell N which is greater than

If we move the contrast coefficient to cell G would see there is no significant difference between New and Control groups. SQRT O M k COUNT qstat L qcrit P xcrit sig IF ABS yes no Figure Selected formulas from Dunn Test This similar to the above and can be viewed version of Nemenyi when sample sizes are unequal. DIST stat TRUE. When we press the OK button result shown right side of Figure is displayed. I guess just got lucky and find the numbercrunching of statistics to rather fascinating.

You shouldn t change the k value for either test. My contact information is the About Author page. a
I really appreciate that you have been an active participant in the Statistics community over several years and made important contributions. but when I have the direction of pair swapped and assigned with larger Rmean get
This test equivalent to where zcrit NORM. So my data set contains proteins for mouse and the abundances of each
