The article presents results of processing the anthropometric data, obtained via measurements of the following ergonomic characteristics: «body height», «side arm reach», «shoulder height from the floor», «elbow height from the floor». Five hundred men of Russian nationality aged from 20 to 55 years from the Orel region have been measured. The obtained material was grouped by means of discrete description for subsequent use and for determination of typical values for the studied traits. Statistical characteristics of value variability for each trait have been defined during processing of the empirical data using variational statistics. This revealed the main variation patterns for the results and allowed to choose a type of theoretical distribution – normal distribution. The hypothesis testing for the compliance with the theoretical law using Kolmogorov’s criterion indicates that differences between empirical and theoretical frequencies are insignificant. As a result, it is possible to state that normal distribution reflects the essential characteristics of the experimental data and can be adopted as a model for the studied traits. Measures of skewness and kurtosis were applied in the analysis of the empirical distribution. All values of skewness and kurtosis are insignificant, which allows us to state that deviation of statistical distribution from the normal is insignificant. In this work values of the studied ergonomic characteristics corresponding to 1, 5, 50, 95, 99 percentiles are defined. This values can be used for designing equipment and for ergonomic calculations and analyses. As a result of correlation and regression analysis, models were developed, allowing to determine values of the effective traits «side arm reach», «shoulder height from the floor», «elbow height from the floor» from a value of the factor trait «body height». Existence of high-degree correlation between considered ergonomic characteristics as indicated by the values of the correlation coefficient is established. The test on significance of correlation and regression parameters is performed using Student’s criterion. The results make it possible to recognize that these parameters are significant.
