Raven's Progressive Matrices Test Correlations with Measures of Lorge-Thorndike and Wechsler Intelligence Tests.
Purl, Mabel C.; Curtis, Jonathan
The relationship of the Progressive Matrices Test (PM) to the Lorge-Thorndike Intelligence Test (LTIQ) and the Wechsler Intelligence Scale for Children (WISC) is examined. Predictive power of these measures with respect to a number of achievement measures was also investigated. The initial sample consisted of 242 first graders and 281 second graders; 182 sixth graders constituted a second sample. A breakdown of the sample by sex and ethnic group is given in Tables 2 through 7. Table 1 gives correlations of the PM with the LTIQ and the WISC and its subscales for each grade considered, for all groups combined. Results indicate that the PM is more predictive of verbal abilities for females than for males. For minority children, the scores associated with the PM, the scores associated with the LITQ, and the Wechsler and its subscales, showed a low and erratic relationship, indicating that the PM measures a dimension of intelligence relatively untapped by the other instruments. However, the PM was found to be a poor predictor of reading or arithmetic achievement for the sixth grade Mexican-American sample, but for all other groups it provided substantial prediction in most cases. The LTIQ was found to be far superior to the PM and WISC as a predictor with all groups. (LR)
