The participants achieved an overall accuracy of 76.04% across the two studies. The accuracy was considerably higher for the video-based study (83.33%), as compared to the 'in situ' study (68.75%), with close to statistical significance using a McNemar's mid-p test on the overall binary categorical **data** (p = 0.057), and actual statistical significance only for expert 1 (p = 0.031). The same test showed no statistical significant difference in accuracy between all pairs of raters (p ≥ 0.125 for all pairs), regardless of the type of interaction (video/real). There also seems to be a relationship between the level of experience and the accuracy of the participants. The accuracy results are summarized in Table 2 and the left side of Table 3.
