Descriptive Statistics for Baseline Simulation at Different Selection Cut Points (Z-Score Metric)

M = 0; SD = 1. Note: Mean scores and standard deviations represent the mean score from the two simulated datasets (i.e. the upper and lower bound). Bold = Baseline scenario (Scenario 1); Test 1–Test 2 r = .75; pretest - posttest r = .85 (both Test 1 and Test 2); Test 1 pretest - Test 2 posttest r = .61 – .75.
