Abstract: The statistical dispersion refers to the degree of dispersion of a set of data values. The dispersion analysis is based on the grouping method. Through this one the influence on the resulting characteristic of the factors recorded as essential (determinant) is separated from the influence of the casual (accidental) factors. The model of dispersion analysis is based on the hypothesis that the means conditioned by the grouping factor are representing typical values getting formed at the level of each group while the general mean (y) is the typical value for the entire collectivity.
