It is well known that the sociometric approach is useful in the study of group social structure to include, for example, student class groupings. In this paper, the authors present a method for measuring and evaluating sociometric tests. After first discussing various aspects of current methods, particularly as related to content validity and sociometric test data reliability, they present a new multi-valued measurement method designed to improve both validity and reliability. Sociometry involves the quantitative measurement of group relationships and the use of graphic representations or sociograms to analyze group structures. The authors go further by describing a method of analysis involving a "fuzzy clustering" method, then showing its usefulness in understanding changes in group structures and individual relationships.
