q3 · i? · causal · r2

Random-effects regression (Panel B, with control variables) on the manipulation check in a two-period wait-list controlled field trial of 116 German primary school children; the treatment effect on syllable stress awareness was "𝛽 = 4.30" with p < .001. Contrast analyses confirmed the effect in both training periods.

"The analyses revealed that Prosodiya had a significant training effect on children’s syllable stress awareness, 𝛽 = 4.30,𝑆𝐸 = 0.66,𝑡(303) = 6 .51,𝑝 < .001, see Table 2 Panel B (3)."
