I have 2 independent samples (groups), each group contains 10 experimental values of variable T and their standard deviations (errors). I need to do intergroup statistical analysis, i.e. to elucidate whether there is significant difference between 2 groups in terms of variable T. I chose non-parametric Mann-Whitney test for doing such analysis. The question is: should I take into consideration standard deviations of my experimental data? If yes, how can I take into consideration the standard deviations in Mann-Whitney test?
