Chapter 10: Multidimensional Scaling

100 Chapter 10: Multidimensional Scaling Multidimensional Scaling (MDS) is a series of techniques that helps the analyst to identify key dimensions underlying respondents evaluations of objects. It is often used in Marketing to identify key dimensions underlying customer evaluations of products, services or companies. Once the data is in hand, Multidimensional Scaling can help determine: what dimensions respondents use when evaluating objects how many dimensions they may use in a particular situation the relative importance of each dimension, and how the objects are related perceptually The purpose of MDS is to transform consumer judgments of similarity or preference (eg. preference for stores or brands) into distances represented in Multidimensional space. The resulting perceptual maps show the relative positioning of all objects.
