Based on the Discriminant Analysis report, the mid-point cut-off method yields a cut-off value of 1.499 (cell E26) for this data. Using this cut-off value, the model correctly classified 18 out of 20 cases, resulting in a classification accuracy of 90%. Therefore, the best choice is to use GMAT scores, verbal, and quantitative as predictors and a mid-point cut-off value of 1.499 to evaluate graduate school applicants.
