Abstract

The goal of this book is to understand histograms, such as Figure 1.1. The figure is taken from Ghiselli’s classic 1966 book The Validity of Occupational Aptitude Tests and is his Figure 2-4. It shows histograms of observed correlation coefficients called validity coefficients. The problem is to model such histograms. Specifically, what might be a parent distribution for such histograms? How many different population correlation coefficients, if more than one, might have given rise to the data? How variable might be the population correlation coefficients? Can their values be estimated?
