q2 i? A two-sided Kolmogorov-Smirnov test comparing mistake frequency per chest compression between the feedback and control groups found no significant difference (KS statistic 0.034, p-value 0.54). → Di Mitri 2022

q2 · i? · causal · r1

Comparison of 20 sessions from 10 participants (feedback vs control) on mistake frequency per chest compression; the KS test yielded "a KS statistic of 0.034 and a p-value of 0.54", so the null hypothesis of identical distributions could not be rejected.

"We obtained a KS statistic of 0.034 and a p-value of 0.54, meaning we could not reject the null hypothesis."
