ERIC ED347191: Rank Order and Paired Comparisons

More Book Details

Description of the Book:

Three case studies are presented demonstrating the application of straight-forward Rasch techniques to rank order data. Paired comparisons are the simplest form of rank ordering. A consumer preference test with 56 pairs of cups of coffee tasted by each of 26 consumers illustrates analysis of these rankings. When subjects are allowed the option of “no difference,” an approach analogous to a rating scale is used. Data from a study by A. Springall (1973) with about 28 assessors judging the flavor strength of a product illustrate analysis of the situation in which ties are allowed. A convenient method of constructing measures from rank orders is to regard the rankings as ordered categories on a rating scale. Data from D. E. Critchlow (1985) illustrate partial rankings of three top choices of crackers by 22 small boys and 16 mothers. These approaches demonstrate methods of producing measures from rankings by judges.

Four figures and six tables present details of the analyses. A nine-item list of references and three appendixes of preference data are included. (SLD
