Summary: When analyzing experimental data, a number of important typical problems arise. These include, in particular, tasks such as checking the homogeneity of two numerical sets, checking the randomness of elements of an experimentally obtained numerical set, checking the independence of elements obtained experimentally with a numerical set, and the like. These problems are formulated in the form of statistical hypotheses. In this paper, we focus on the so-called non-parametric statistical methods of testing statistical hypotheses. In particular, methods such as the Wilcoxon method, the sign method, and the series method are considered. Sciences of Europe # 50, (2020) 11 The paper reveals the essence of these three criteria for testing statistical hypotheses. The relation of these criteria to the normal law of distribution of a random variable is shown. We support the theoretical schemes with specific examples, in particular, taken from our pedagogical experiment.
