21 Kruskal-Wallis test
стат. критерий Крускала-Уоллиса (непараметрический критерий для сравнения трех или более выборок, основанный на проверке двух гипотез: о том, что у всех выборок идентичная функция распределения и о том, что как минимум две из выборок отличаются только видом распределения относительно среднего)See:The Kruskal-Wallis test is a nonparametric test to compare three or more samples. It tests the null hypothesis that all populations have identical distribution functions against the alternative hypothesis that at least two of the samples differ only with respect to location (median), if at all. It is the analogue to the F-test used in analysis of variance. While analysis of variance tests depend on the assumption that all populations under comparison are normally distributed, the Kruskal-Wallis test places no such restriction on the comparison. It is a logical extension of the Wilcoxon Mann-Whitney Test (see listing). -
22 Parametric Test
Параметрический критерий используется для проверки гипотезы о различии (или сходстве) между показателями разных групп, если распределение выборок является нормальным. Наиболее распространенным параметрическим методом оценки различий между сравниваемыми средними значениями независимых выборок является критерий Стьюдента, или t-критерий.
