مقارنة اختبار دونت المعدل مع اختبارات المقارنات المتعددة الاخرى لتصميم تام التعشية CRD

In this research we worked comparisons for some multiple comparisons tests including original Dunnett test(For comparing a control treatment and another treatments that supported in the experiment) with new method suggested in 3122 by Conagin,Barbin and Demetrio called modified Dunnett test to determine the better depending on the criteria of power of the test dependent experiments with CRD:Completely Randomized Design for case of equal replicates for each treatment with the addition case of unequal replicates for treatments. We worked an empirical side (simulation) to calculate power of the test and make the comparisons , then we reached that the MDT superiority over the other multiple comparison tests that studied in this research except LSD test which showed equality power of the test with MDT
