Subclaims¶

q3 i3 An independent samples t-test found a significantly higher mean GEARS score for the XR-trained group (16.73) versus the no-training group (13.91), with a large effect size (d = 0.964, p < 0.001). → Bickford Michael 2025

q3 · i3 · quant-synthesis · r3

Independent samples t-test comparing mean GEARS scores between XR-trained (n = 63) and no-training (n = 60) groups. The effect size was "strongly in favor of the VR trained group" at 0.964 with a 95% CI of [0.589, 1.336].

"The independent samples t test yielded an effect size strongly in favor of the VR trained group; 0.964 (95% CI 0.589 to 1.336). The threshold for a large effect size is 0.8"
