An Evaluation of Procedures for Computing and Ability--Achievement Discrepancy Score.
Berk, Ronald A.
Journal of Learning Disabilities, v17 n5 p262-66 May 1984
Nine procedures assessing the magnitude or statistical significance of ability-achievement discrepancy dealing only with magnitude were evaluated and found to possess one or more serious statistical deficiencies. The approach with the greatest potential involves assessing the statistical significance (reliability) of a discrepancy score and then estimating the discriminative efficiency (validity). (Author/CL)
