The twelve indices were Simpson's Concentration Index ("ell"), Simpson's Index of Diversity, Hurlbert's Probability of Interspecific Encounter (PIE), Simpson's Probability of…

This article defends research evaluating similarities and differences in psychometric performances of students with learning disabilities (LD) and students with low achievement (LA), which concluded that psychometric test performance alone was an insufficient basis for differential diagnosis. Recent criticism of the research by Kenneth Kavale and…
