q2 i? The corrected coefficient between Terman Arithmetic and the English criterion was 0.293, which the authors take as evidence of two distinct abilities. → Wyman 1921

q2 · i? · associational · r1

High School English study: the arithmetic exercise in the Terman Group Test was included in the battery of 94 high school seniors to see whether it would fall into a low position against the criterion of teachers' English grades. The corrected coefficient is reported but is an attenuation-corrected value with an estimated criterion reliability, so no magnitude is coded.

"Since this corrected coefficient is so low (0.293) it affords objective evidence that arithmetic and English ability constitute two separate capacities."
