Subclaims¶

q3 i? A random-effects meta-analysis found XR-trained novices had higher GEARS scores than those with no additional training (Cohen's d = 0.75), but this was not statistically significant (p = 0.23). → Bickford Michael 2025

q3 · i? · quant-synthesis · r3

Meta-analysis comparing XR training to no additional training on GEARS scores. The effect was described as "large" (d = 0.75) but "not statistically significant" (p = 0.23).

"A random-effects analysis of the GEARS scores showed that participants with extended reality training had higher GEARS scores than participants without any additional training. With the training having a large effect on the scores (Cohen’s d = 0.75, 95% CI [−0.48, 2.05]). However, this result is not statistically significant (P = 0.23)"
