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 distributions of grades for day and night courses were closely similar within each group across years but differed between groups, supporting separate standards. → J. L. Zerbe 1917

q2 · i? · associational · r1
Descriptive tabulation separating day and night course grades for 1912-13, 1913-14, and first semester 1914-15. Each group's distribution was stable across years, and the author concludes grading "ought to be based on different standards" for the two groups.
"The close proximity of the distribution for the day and night courses respectively from year to year indicates that the grading for the day and the night students ought to be based on different standards."
