Abstract
Paper presents usage of statistical methods for an analysis of run of parallel structure. There was reported a problem that actuators of vertical axis are not uniformly loaded. Variance of acceleration record from each actuator were analysed and compared. There was performed normality test with Chi-Square. To compare the variance of acceleration there was used a non-parametric Kruskal–Wallis test. To identify a problematic actuator there was used a multiple comparison test and matrix of correlation coefficients with graphic output was constructed. The analysis pointed out on the most problematic actuator. Gathered information was used for further optimization and improvement of structure.
