Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? A random-effects meta-analysis found no statistically significant difference in GEARS scores between XR-trained and dry lab-trained novices (Cohen's d = -1.09, p = 0.30). → Bickford Michael 2025

q3 · i? · quant-synthesis · r3
Meta-analysis comparing XR training to dry lab training on GEARS scores. The result was "not statistically significant" with Cohen's d = -1.09 and a 95% CI of [-3.17, 0.98].
"A random-effects analysis of the GEARS scores showed that participants with extended reality had lower GEARS scores than those that were trained in extended reality. (Cohen’s d = −1.09, 95% CI [−3.17, 0.98]). However, this result is not statistically significant (P = 0.30)"
