q3 i? Reading Ability C correlated 0.85 with the Terman Group Test, higher than Visual Vocabulary (0.76) or any weighted reading test. → Wyman 1921

q3 · i? · associational · r1

Grade VIII reading study: the second criterion combined all tests weighted by five independent expert judges' average values as measures of silent reading ability. The article asks whether "is our criterion for reading ability really a measure of general intelligence, or does the Terman Group test measure reading ability?" The correlations are reported as raw coefficients with probable errors, so no standardised magnitude is coded.

"Here the highest correlation is with the Terman Group test; and, as the correlation is a high one, we must conclude they measure very much the same thing."
