O A Kharkova, A M Grjibovski · Экология человека · 2014
In this paper we present theoretical principles of the use of non-parametric criteria for comparing two independent groups. Practical examples are presented with detailed explanations of the use of formulas as well as step-by-step algorithm on how to use STATA software for Mann-Whitney and two-sample Wilcoxon tests with subsequent interpretation of the outputs.
