• A simple procedure for testing for differences in sexual dimorphism between populations

      Lewis, Stephen J.; Chester College of Higher Education (InterStat, 2004)
      Using point bi-serial correlation, an approach to the biological problem of comparing differences in sexual dimorphism between populations is presented. In particular, a way of deriving the point bi-serial correlation coefficient from summary statistics (means, standard deviations and sample sizes) is given. This bypasses the need for access to raw data.
