EVALUATION OF MATHEMATICAL EXPECTATION USING A CONFIDENCE INTERVAL (ON THE EXAMPLE OF THE CONCEPT “CULTURE” RESEARCHING IN YAKUT LANGUAGE)

Abstract

The study is devoted to the description of the results of using the “confidence method” from mathematical linguistics to confirm the results of a free associative experiment conducted among native speakers of the Yakut language as part of the study of the concept “culture”. The experiment involved 2000 respondents, who presented associative reactions to 15 stimulus words representing the studied concept. The paper presents the possibility of using the “confidence method” for experimental confirmation of the reliability of the obtained reliability coefficients. A method for determining the confidence interval for the share of a feature and a method for determining the required volume of the corresponding sample are proposed. The used method proves the effectiveness of its application to confirm that if the same number of respondents participate in the experiment, the same results can be achieved.
