Large-Sample Test Intercorrelations. Technical Report 1983-2.
The correlations of each of the 22 tests in the Johnson O'Connor Research Foundation battery with all other tests in the battery are listed. Four fairly large samples are used, each including cases of one sex and a narrow age range. These cases come from a file of 3,555 examinees tested between June 1981 and the fall of 1982. The purpose of computing and publishing these correlations is to provide a resource to be used in future research. No attempt is made in this report to interpret the individual results. The correlations are, in general, similar to those that have been reported previously for smaller samples. There may be a tendency for the present correlations to be slightly higher than earlier ones; this could be attributed to the care which has been taken in using only comparable forms of each test, and to recent efforts to reduce slight differences in scores obtained by different administrators or offices. The present report also illustrates the unreliability of correlations from small samples; for example, the correlations between Oral Ideaphoria and Wiggly Block, based on samples containing from 61 to 169 cases, range from -.05 to .40.
