Bridges, J. W. (1920). The correlation between college grades and the Alpha intelligence tests. The Journal of Educational Psychology, 11(7), 361-369. https://doi.org/10.1037/h0071462

q3 · i? · associational · r2

Table III reports percentage distributions of intelligence ratings for each academic grade group, plus the whole university (5,950 cases), 28 Phi Beta Kappa electees, and 588 probation students, showing honors students concentrated in Classes I-II and probationers in Classes III-V; no effect size is printed.

"there are also added for comparison intelligence distributions of students elected to Phi Beta Kappa in 1920, and of students placed on probation at the end of the first semester because of poor academic work."
