The monograph presents current methodological, organizational, methodological and practical issues of the measurement and calculation process; elements of human testing are considered, as well as methods of their mathematical and statistical processing, encountered in the course of pedagogical and scientific activities of various kinds of specialists. The main data processing methods are integrated and analyzed, including parametric and non-parametric criteria, correlation, regression, variance and factor analyses, which allow an objective assessment of the entire process. The necessary theoretical information and formulas for calculating rating ratings, most often found in sports and pedagogical studies of both one person and a team, are given. The monograph is intended for students, undergraduates and graduate students of higher educational institutions, specialists in the field of physical education and sports, coaches, as well as researchers from related fields of science who use mathematical and statistical methods in their work in order to effectively solve practical problems.
