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.

q3 i? Children in the Number condition learned significantly more numbers than children in either alphabet condition, with differences surviving multiple-comparison correction. → Piasta 2010

q3 · i? · causal · r2

In the randomized experiment's ANOVA interaction contrasts, Number-condition children outgained LNLS (d = 0.22) and LS (d = 0.71) children on number identification; "these differences remained significant after application of the linear step up procedure".

"children in the Number condition learned significantly more numbers than children in either the LNLS or LS conditions, F(1, 52) = 7.682, p = .004, d = 0.22 and F(1, 52) = 16.123, p < .001, d = 0.71, respectively"
