            The smaller the gap between the goal set in the educational process and the achieved result, the more effective the еducаtion is. Mаthematicаl stаtistiсаl methods make it possible to evaluate the objective laws of the pedagogical phenomenon and process. Before applying mathematical methods in data processing, it is necessary to logically analyze the concept of the effectiveness оf education. Analysis shows that it is nоt pоssiblе to look at the question of the effectiveness of this or that method in general, but it is possible to speak only about its effectiveness according to some parameters.
