Abstract

The aspects of the formulation and processing of the results of pedagogical experiments with a limited number of objects of study are considered. It is shown that when working with narrow specialists or when studying specific properties, one has to be limited to the number of objects that are available to the researcher. A feature of small samples is the difference from the normal law to the distribution of random errors, which leads to a violation of the representativeness of the results. Accepting a reasonable combination of data allows you to form samples of the required volume and then use the arsenal of mathematical statistics to analyze and evaluate research hypotheses
