Comparison of Seriation and Multidimensional Scaling: Two Techniques for Validating Constructs in Physical Education
Korell, Diane M.; Safrit, Margaret J. – Research Quarterly, 1977
Research into statistical validations of constructs in physical education obtained by seriation and multidimensional scaling, revealed that (a) larger matrix sizes produced the most accurate results; (b) as data error introduction was increased, solution accuracy decreased; and (c) seriation produced slightly more accurate results than one- and…
