This book provides a comprehensive and systematic assessment of the application of the McIntosh evenness diversity index to the workplace. Like its preceding companion books, this book offers human resources practitioners and researchers in the nonprofit, private, and public sectors a hands-on guide on how to measure demographic and organizational diversity. Examples of how the McIntosh diversity index is applied to employment data are provided throughout the book. Consistent with its preceding companion books, this book illustrates the use of ordinary least squares, quantile, ridge, robust, and Tobit, regression methods to assess how organizational and workplace factors influence age, ethnic, gender, and organizational diversity.
