Subclaims¶

q3 i? In a subsample with both standardized tests, SYMP Test correlations with mathematics achievement were moderate and significant across all grades (one-digit r = .28; two-digit r = .30). → Brankaer 2017

Brankaer 2017¶

Brankaer, C., Ghesquière, P., & De Smedt, B. (2017). Symbolic magnitude processing in elementary school children: A group administered paper-and-pencil measure (SYMP Test). Behavior Research Methods, 49, 1361–1373. https://doi.org/10.3758/s13428-016-0792-3

q3 · i? · design · r3

Correlational analysis of the subsample of children with data on both standardized achievement tests (n = 942), using z-scores per grade. The paper-and-pencil test correlated with the curriculum-based mathematics test in all grades, with "one-digit r =. 28" and "t w o - d i g i tr = .30".

"In this subsample, correlation coefficients between the SYMP Test and the standardized test for mathematics were moderate and significant across all grades (one-digit r =. 28 ;t w o - d i g i tr = .30; ps < .01)."
