concomitant variation

concomitant variation

an empirical relationship in which the magnitude of a first variable varies with the magnitude of a second variable (see COMPARATIVE METHOD). The concomitant variation or CORRELATION between variables may be used as the test of a CAUSAL RELATIONSHIP between variables. The main causal hypotheses in Durkheim's Suicide (1897) were tested using this method.
