A correlational study among the Wechsler Adult Intelligence Scale-Rivsed, the Graduate Record Examination, and grade point average.

Abstract

The purpose of the study was to examine the relationships among the Graduate Record Examination (GRE) scores, Wechsler Adult Intelligence Scale-Revised (WAIS-R) scores, and undergraduate grade point average (UGPA) for the last 60 hours. Thirty clinical psychology graduate students from a regional, midwestern university were chosen. Their selection was based on the following criteria: 1) they must have been enrolled in the clinical psychology program at Emporia State University, 2) they must have a GRE score on file upon entering Emporia State University, and 3) they must not have taken or have been enrolled in the course PY 841 -Clinical Mental Tests II (The Wechsler scales). After receiving permission from the Human Subjects Committee and each individual via a consent form, each subject was administered the Wechsler Adult Intelligence Scale-Revised (WAIS-R). The WAIS-R tests were administered by five examiners. Next, the subject's GRE scores and the last 60 hours of undergraduate study GPA were obtained. The WAIS-R administrator did not view the subject's UGPA or GRE scores in order to decrease potential examiner bias. At the completion of the WAIS-R testing procedure, the total GPA, GRE and WAIS-R results were utilized in a two step statistical process. First, Pearson product-moment correlation coefficients were calculated. Correlation coefficients ranged from .22 to .94. All variables were significantly correlated at the .05 or .01 level except UGPA with the GRE Quantitative section. Seven independent j-tests were done to yield information concerning gender differences. Statistical significance was not found among the 30 subjects on the seven variables.
