Dear all, My question can be easily misunderstood, so please allow me to briefly explain the experimental conditions. I have measured a variable from 120 individuals in total, 60 of one genotype and 60 of another. The distribution of the complete sample of each of the two genotypes is...

Hi, I noticed that in the following articles data distribution is tested via checking for >10% difference in mean and median. http://www.sciencedirect.com/science/article/pii/0022175996000130 http://www.sciencedirect.com/science/article/pii/002217599500078O However, when I follow the...

so in my minor thesis, i compare 2 groups (deaf and normal children; n1=n2=15) in their forward and backward digit span scores and word-list memory task (wlmt) scores (there are 4 scores: 1st, 2nd,and 3rd trial, and the mean scores of all three trial). in the normality tests, distribution is...
