The Conceptualization and Measurement of Diversity

Daniel G. Mcdonald

John Dimmick

This article defines dual-concept diversity as a two-dimensional construct that holds a central place of study in many fields, including communication. The authors present 12 measures of dual-concept diversity appearing in the literature and assess the differential sensitivity of these measures in capturing the two dimensions. After assessing each measure and eliminating measures that are redundant or computationally intractable, the article compares the remaining measures of diversity in a time series of 30 years of network radio programming. Graphic and statistical interrelationships are presented to facilitate comparison and choice between measures in future research.

Key Words: program diversity • radio programs • television programs • diversity measurement
