Alternative Methods for Combining Several Test Scores
Zakkula Govindarajulu · Educational and Psychological Measurement · 1988
If a battery of tests is administered to the same individual, the question is how to combine the various resultant scores so as to obtain a composite score for prediction purposes. Even if preas-signed weights are used, they may not be the true weights, especially, when the test scores are intercorrelated. In the following the author briefly reviews the existing methods and proposes some new ones for obtaining weights that are best in some sense. Further, he illustrates the methods by using the data on certain city government employees.
