q3 · i? · design · r3

Test-retest analysis in a large sample retested 3–5 weeks after first assessment (n = 1,425). Overall scores summed across the two subtests yielded test-retest correlations "rs between .72 and .86, ps < .01," exceeding the .70 criterion the authors cite for adequate reliability.

"This yielded higher test-retest correlations for these overall scores in all grades (rs between .72 and .86, ps < .01), which suggests that both subtests should be administered at the same time when assessing symbolic magnitude processing."
