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? Distributions of 2014 reading scores in B, C, and D schools were nearly identical, and many students in D and F schools scored as high as students in A and B schools. → Adams 2017

q2 · i? · theoretical · r2

Analysis of Oklahoma student reading score distributions plotted by A–F letter grade (Figure 2), adapted from the authors' 2015 report to the Oklahoma State Department of Education, shows within-grade distributions resembling the state population distribution.

"Distributions of reading scores in B, C, and D schools are nearly identical. F schools had more low-performing students than the population, but arguably, the distribution of reading scores is not much different than that of the population."
