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 Grade 1 one-digit correlation with mathematics achievement differed significantly from those in Grades 4, 5, and 6, whereas two-digit correlations did not differ between grades. → Brankaer 2017

q3 · i? · design · r3

Fisher's z comparison of correlation coefficients across grades in the correlational analysis of the large sample. The Grade 1 one-digit correlation differed from Grades 4, 5 and 6 (e.g., "z =2 . 2 2 ,p = .03" for Grade 4); two-digit correlations showed no significant grade differences.

"For the one-digit subtest, the correlation for the Grade 1 children differed significantly from that for Grade 4 children ( z =2 . 2 2 ,p = .03), Grade 5 children ( z= 2.40, p= . 0 2 )a n dG r a d e6c h i l d r e n(z =2 . 3 8 ,p =. 0 2 )."
