摘要：In order to study the connections between economic phenomena and processes is necessary first to know their objective form of manifestation. Economic and social phenomena are not usually uniquely determined, being the result of the influence of many causes. In this connection system, the dependency relationships don’t have all the same importance, the action of some of them compensating each other. In the statistical analysis of the relationship of dependence between phenomena, it is important the issue of measuring the relationship between two or more characteristics used in studies of economic and social mass phenomena. Thus, it should be determined whether there is a relation of dependence between the characteristics, and if so, the dependence should be expressed through a correlation indicator which may express the degree in which one phenomena contributes to other phenomena.
