Subclaims

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q3 i1 For 200 senior students, subtest correlations with point-hour ratio ranged from r = .17 for Test 3 to r = .37 for Test 7. → Bridges 1920

Evidence

Bridges 1920

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 · i1 · associational · r2

Correlations between point-hour ratios and each Alpha test taken separately for the 200 senior students, whose six-semester point-hour ratio "has therefore greater validity as a measure of academic standing"; the printed effect sizes range from r = .17 to r = .37.

"The correlations vary from .17 in the case of Test 3 to .37 in this case of test 7."
