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? Welch's t-test found a statistically significant improvement in the Pscore of the experiment group compared to the control group on test 3 (z = −2.1538, df = 29.757, p = 0.01974). → Damacharla 2018

q3 · i? · causal · r1
Controlled user study with 36 novice participants (19 experiment, 17 control) performing a massive hemorrhage tourniquet task over three training-testing iterations. The experiment group's "Pscore of the experiment group in test 3" was significantly higher than control's (z = −2.1538, p = 0.01974); no effect size is printed.
"Welch ’st - t e s t found statistically significant improvement in the Pscore of the experiment group in test 3 compared to the control group in the same test (z = −2.1538, df = 29.757, p = 0.01974)."
Discussion¶
Related Claims¶
- Reporting errors were significantly reduced in every training session of the VBSA-trained group compared to the control group, and implementation errors were reduced from first to last training session — related
- Repetitive training with the synthetic assistant produced statistically significant performance growth across successive tests, whereas the control group's growth was largely insignificant — related
- Training with the voice-based synthetic assistant caused no statistically significant loss in task execution time and no significant time difference between groups across testing scenarios — related
