Comparison of the Stanford-Binet Intelligence Scale: Form L-M and the Stanford-Binet Intelligence Scale Fourth Edition

Composite standard age scores and the four Area standard age scores of the Standard-Binet Fourth Edition (SBIV) were each compared to the Stanford-Binet Form L-M IQs of 30 11-yr.-old public school children. The Pearson correlation of the total scores was .72, while the correlations of the SBIV Area scores and Form L-M IQs ranged from .81 (Verbal Reasoning vs L-M), .72 (Quantitative Reasoning vs L-M), .47 (Short-term Memory vs L-M) to .40 (Abstract/Visual Reasoning vs L-M). Classification by IQ suggested that both tests tend to categorize individuals similarly, and no sex biases were obtained.
