q3 · i? · associational · r1

Independent-samples t-test in the same 55-participant sample comparing native signers (deaf parents, ASL acquired before age three) with non-native signers on the combined Bilingual Ability score. The study reports "t (53) = 4.12, p = 0.000" with the printed group means; no effect size is printed.

"A t-test indicated that native signing of ASL was significantly related to participants’ bilingual abilities , with native signers (M = 3334.51, SD = 618.59) exhibiting more proficient bilingual abilities than non-nativ e signers (M = 2327.35, SD = 779.33), t (53) = 4.12, p = 0.000."
