q2 i? The percentage of non-table errors in multiplication correlated negatively with hearing age in children with CI (r(45) = −0.30, p < 0.05) but not in controls (r(49) = 0.11, n.s.), with a significant Fisher's Z difference (Z = 1.97, p < 0.05). → Pixner 2014 q2 i? Latency on borrow subtraction problems correlated negatively with hearing age in children with CI (r(45) = −0.28, p < 0.05, one-sided) but not in controls (r(49) = 0.14, n.s.; Fisher's Z = 2.01, p < 0.05). → Pixner 2014 (2)

Pixner, S., Leyrer, M., and Moeller, K. (2014). Number processing and arithmetic skills in children with cochlear implants. Frontiers in Psychology 5:1479. https://doi.org/10.3389/fpsyg.2014.01479

q2 · i? · associational · r2

Correlational analysis within the CI group on multiplication error types; "the percentage of non-table errors was correlated significantly with hearing age in children with CI", consistent with increasing automaticity of fact retrieval. The control-group correlation was not reliable and the between-group difference was significant by Fisher's Z-test.

"A correlation analysis indicated that the percentage of non-table errors was correlated significantly with hearing age in children with CI [r(45) =− 0.30, p < 0.05] indicating that with increasing hearing age fewer non-table errors were committed."

q2 · i? · associational · r2

Correlational analysis linking CI children's hearing age to borrow-subtraction latencies; "with increasing hearing age borrow subtraction problems were solved faster", while the control-group correlation was not reliable and the difference between correlations was significant (Z = 2.01, p < 0.05).

"The correlation analysis revealed the to-be-expected reliable negative correlation in children with CI [r(45) =− 0.28, p < 0.05, tested one-sided] indicating that with increasing hearing age borrow subtraction problems were solved faster."
