Studies of organizational behavior and other managerial phenomena frequently include variables which are not readily measurable by cardinal or ratio scales. Variables of this nature occur, for example, when investigating the relationship between a supervisor's span of control and (i) dissimilarity of subordinate's jobs, (ii) supervision received from other executives, (iii) geographic concentration of subordinates, and (iv) personal assistants. The (0, 1) variable technique, explained and illustrated here in terms of this example, offers the researcher a superior analysis for those sociological, psychological, and managerial phenomena for which no metric has yet been developed. The authors believe that this is one of the most useful statistical techniques available to the management scientist.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
