Significance Testing of Congruence Coefficients: A Good Idea?

Davenport, Ernest C., Jr.

Educational and Psychological Measurement, v50 n2 p289-96 Sum 1990

The properties of Tucker's congruence coefficient--an index used to help determine the equality of latent structures for different subgroups on a common set of test items--are explored. An example using data from 1,370 subjects in the National Assessment of Educational Progress 1976 mathematics assessment illustrates the index's use. (SLD)
