ABSTRACT
In this chapter, the authors evaluate an example of the unfolding technique's use in obtaining interval-scale information under the ideal conditions of error-free measurement. They present their evaluation of the effectiveness of the technique under conditions in which error is present in the data. The authors also present suggestions for possible additional applications of the technique. Psychologists have developed a scaling technique which, by allowing the assignment of an approximate interval value to some attribute of a subject for which there exists a set of ordinal values, yields an ordered-metric scale. Since Guttman scaling method could prove useful in various social science applications, to adapt this technique for use by social scientists other than psychologists. The most complete discussion of the use of nonmetric scaling techniques in geographical research is found in Reginald Golledge and Gerard Rush ton. The unfolding technique is grounded in a more comprehensive "theory of data".
