Abstract
In this paper the simplest variant of analysis of variance is under consideration. Three examples from textbooks by Lakin (1990) and Rokitsky (1973) were re-considered. It was obtained that traditional one-way ANOVA and Kruskal - Wallis criterion can lead to unreal results about factor's influence on value of characteristics. Alternative way to solution of the same problem is under consideration too.

Keywords analysis of variance;tests for normality;goodness measure.
