Validity Indices of the D-48 Test and the D-70 Test

Abstract

The D-48 and D-70, two forms of the Domino Test, were compared for equivalence and predictive ability. The tests were administered to 321 undergraduate students, and criterion scores obtained were over-all GPA, ACT score, and test scores in educational psychology. Correlations between the two forms of the Domino Test were relatively low (.58 to .69). Other results confirmed the parallelism of the two tests. Support was provided by the equality of means and standard deviations and approximately equal correlations with outside criteria.
