The aim of this paper is to present new possibilities of the statistical analysis of pretestposttest data types measured in a pedagogical experiment. These possibilities will allow us to eliminate the effect of so-called disruptive independent variables that could adversely affect a dependent variable and thus, the research results. By using a model example, we present the design of a suitable experimental plan. Further, we illustrate advanced statistical techniques - Analyses of Variance and of Covariance using a real example.

Keywords: Pedagogical experiment, pretest, posttest, analysis of variance for difference scores, analysis of covariance
