  1. Cohen’s d reflects the difference between the means divided by the standard deviations for those with and without presenteeism. A difference of 0.2 is considered small, 0.5 is medium, and 0.8 is large. As Cohen’s d value increases, the lower percentage of overlapping values are observed between groups
