Abstract : Although ranking is often used by research personnel and by others working in supervisory and management situations, there has been practically no development work done on the method itself. Many techniques for accomplishing rank-ordering are devised, but their efficacy is rarely tested. In an attempt to determine the most effective sorting procedure to arrive at accurate rankings, a task was selected that permitted an objective measure of error. 54 cards were prepared that showed pairs of circles differing in area by graduated amounts. The task was to order the cards by size of difference in circle area. 5 samples of 52 airmen were each directed to sort the cards by one of 5 methods. 4 methods were structured in varying degrees; in the fifth, subjects were free to sort as they pleased. Analysis of variance demonstrated significant differences between methods. The free-sort method yielded the least average error, suggesting that for judgments of the type used in this study, there is no gain in accuracy of ranking from specifying the method of sorting.
