The correct application of the statistics methods problem in the scientific papers on ballet pedagogics

Abstract

An experimenter often makes the mistakes when he is transferring the characteristics of the object of study in a measurable state to formalize the initial data for further processing statistical methods. Most often, these errors are related to the inadequacy of the measurement scale, incorrect aggregation of individual data, using linear correlation coefficient to the members of the rank scale, rather than absolute terms and without assessment of its reliability. This article discusses the intricacies of correct choice of the scale of measurement, of the transition from one scale of measurement to another, of the indicators aggregation, of the use of correlation analysis. Correct or incorrect solution of a statistical problem is illustrated by examples of research papers on ballet pedagogy.
