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.

q2 i? The correlation between Binet IQ and Healy Picture Completion time is r = -.05 ± .093, a negative correlation the author again calls insignificant. → E. B. Skaggs 1920

q2 · i? · associational · r1

A second product-moment correlation from the same 65-case comparison, using Healy Picture Completion time records rather than scores. The article notes "here is a negative correlation" and that the probable error again exceeds r; no effect size beyond the coefficient is printed.

"The correlation between Binet I.Q. and Healy Time: r = - .05 ± 093."
