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 analysis compared the COVID year student group's achievement with that of their pre-pandemic peers to track the gap between the cohorts. → Karyn Lewis 2023
