A punched card procedure for use with the method of paired comparisons

Abstract

A step-by-step procedure for setting up paired comparison materials applied to ratings of workers on job performance is described here. This kind of task (25 names in variable list, which means a deck of 300 pairs that must be produced) takes an experienced operator 40 minutes to complete, including the scoring subsequent to the preparation. If a typewriter were used to prepare the pairs, 12 to 16 hours of clerical labor would be required in preparation and scoring. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
