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? In surveys already made, clear-cut differences were found between fast and slow sections, between schools in pupil ability and in adjustment to capacities, and between average school children and children in institutions. → Pressey 1920

The author's interpretation of findings from the surveys conducted with the scale across several Indiana cities; no effect sizes or statistics are printed for these group differences.
"In the surveys already made, clear-cut differences have been found between "fast" and "slow" sections, between schools, both in the ability of the children attending them and in the amount of adjustment made by the schools to the capacities of the children, and between average school children and children in institutions."
