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? There is a positive correlation of small amount between first and final tests in the practice series, so students who excelled at the start tended to retain their superior position after practice. → Dearborn 1918

Conclusions section, based on the class practice-series records (rank correlation between initial and highest practice records reported as R = 32, ±7). Students "tend to hold the same relative rank in the first trials as in the last trials of the practice."

"It appears from the figures we have given that there is a positive correlation of small amount between the first tests and the final tests of students in the practice series."
