normative dataset currently contains
673
participant records collected between
Jun 11, 2026
and
Aug 11, 2026
.
This psychometric dataset currently includes 673 anonymous participant responses collected through voluntary participation. The observed mean score was 49.22 with a standard deviation of 14.71, indicating moderate score variability within the sampled population. Internal consistency reliability analysis demonstrated good reliability (Cronbach alpha = 0.861). Observed skewness (0.36) and kurtosis (-0.02) were examined as indicators of distribution quality. The score distribution appeared reasonably balanced and did not suggest substantial departures from normality.
