Abstract

The thesis discusses the basic concepts and methods of testing statistical hypotheses. The concepts of statistical, null and alternative hypotheses, their content and purpose are described. The classification of statistical significance criteria, including parametric, non-parametric and consistency criteria, is considered. The main distributions used to test hypotheses are presented, including the normal distribution, χ², Student’s and Fisher’s distributions. Particular attention is paid to the practical application of criteria for testing the normal distribution in a sample. The conditions for testing the hypothesis and the methods of analysis used are presented.
