A population of individuals is considered, upon whom measurements are made in [k] different categories. The total score of an individual is then taken to be the sum of measurements in each category. Since [k] is usually a large, or relatively large, number, a method using the multiple correlation coefficient is derived that seeks out those categories among the original [k] categories that can be used to predict the score or response of an individual who is yet to undergo the test. 10 pp. Ref.
