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? Haines outlines a point scale and a year scale for measuring the intelligence of the blind, with norms based on 142 cases and detailed application instructions. → Kohs 1917

q2 · i? · review · r2
Annotation of Haines (1916, Psychol. Monogr. Vol. 21, No. 1, 86 pp.). Companion entries report 224 blind persons examined (ref. 168) and a provisional point scale suggested from a survey of the Ohio State School for the Blind (ref. 169).
"Outlines a point scale and a year scale for measuring the intelligence of the blind and gives norms based on 142 cases."
Discussion¶
Related Claims¶
- The year scale and the point scale yield disparate results and differ in diagnostic accuracy for delinquent populations, per Haines's studies — related
- Intelligence-test scores overlap substantially across non-consecutive grades, with some fourth graders scoring above the fifth-grade norm — related
