Abstract
A questionnaire may consist of duplicated or similar items. This study finds the duplicated or similar items by using the MDS and the cluster analysis of response patterns. By identifying the characteristics of the cluster, those items are combined into a representative item. The similarity of items is measured by the mutual information.
Keywords
Entropy; mutual information; cluster analysis; multidimensional scaling(MDS);
