You performed a reaction time experiment in which you randomized subjects to two conditions. You analyze the results with the Mann-Whitney-Wilcoxon U test and obtain a two-sided p value of 0.031. You then notice that the reaction times were recorded inaccurately; you need to apply a square-root transformation to get accurate reaction times. Will this change he following statistics? Check the ones that will change. (a) Mean (b) Mean difference (c) Pooled standard deviation (d) P value from the U test
