Abstract : A new method of selecting and weighting the variables in a naval testing battery was introduced. This method, called the short battery (SB) method, consisted of selecting and weighting several sub-testings rather than the total battery as is traditionally attempted. The size of each short battery was set at the number of significant factors common to both the criterion and predictor set. This new method was compared against the traditional approach in terms of the cross-validation of their respective weight vectors. This comparison was conducted under all combinations of sample size (50, 100, 250), predictor pool size (6, 12, 18), within-cluster similarity (high, moderate, low) and criterion-free homogeneity (high vs. low). The SB method was found superior under all combinations of parameters except for a select combination of conditions which introduced true suppressor effects into the multiple. (Author)
