Ten-Year Stability of Verbal and Nonverbal IQ Scores
Peer reviewed Peer reviewed
Hopkins, Kenneth D.; Bracht, Glenn H. – American Educational Research Journal, 1975
The results of this study show that, below ten years of age, stability in IQ scores from group verbal tests is considerably below that for Stanford-Binet. Non-verbal IQ scores were found to have substantially less stability than verbal IQs. (Author/DEP)
