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? Correlations of comprehension with single school subjects are low: spelling 0.40, arithmetic 0.24, writing 0.10; rate shows similar values. → Arthur I. Gates 1921

q2 · i? · associational · r1
From Tables XVIII and XIX correlations across grades III-VIII, the article reports reading's correlations with single subject composites are low, while the composite of school achievement correlates about 0.70, largely because reading is included in it.
"Correlations of comprehension with spelling average 0.40, with arithmetic 0.24, with writing 0.10. The correlations of these subjects with rate are about the same."
