The article reviews an important section of economics - correlation analysis: the terminology is given, the properties of the nominal measurement scale are considered, methods of revealing and evaluating the degree of correlation between phenomena - correlation coefficients are given. On the basis of the collected information, a study of the consistency of S.G. Svetunkov's new correlation coefficient for nominal data has been made. Calculation of the coefficient values on various data allowed us to conclude about its consistency.
