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? On a descriptive hidden decimal task, 86% of children identified 0.XXXX as greater than 0.X, consistent with whole number logic. → Malone Amelia S. 2017

q2 · i? · associational · r2
Descriptive hidden decimal task (Resnick et al., 1989) administered for descriptive purposes only; only 14% answered correctly on the first item and 45% on the second item.
"Instead, 86% of children identified 0.XXXX as the greater decimal, which is consistent with whole number logic."
