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? The bifactor model fit better than the two-factor model for print knowledge, and the general factor accounted for approximately 79% of variance in total print knowledge scores. → Goodrich J. Marc 2017

q3 · i? · associational · r3

Omega statistics from the bifactor print knowledge model in the sample of 858 preschoolers; "approximately 79% of variance in total print knowledge scores was due to the General factor". The two-factor correlation was r = .61, p < .001.

"Omega statistics indicated that approximately 79% of variance in total print knowledge scores was due to the General factor, approximately 17% was due to the Spanish factor, and approximately 3% was due to the English factor."
