q2 · i? · causal · r1

Cognitive engagement results from the efficacy verification section of the quasi-experiment (eight students per modality, five-day storytelling). The article reports "a statistically significant improvement, p<.05" with a +30.00% gain; no effect size is printed.

"The robot group displayed a statistically significant improvement, p<.05 (pre-test: M,= 66.67, σ =18.86; post-test: M,= 86.67, σ =10.08; +30.00%)."
