Table 2.
Mean | Median | CV | Min | Max | MW | |
---|---|---|---|---|---|---|
Men | 2.8% | 1.2% | 158.9% | 0.1% | 20.4% | 375 ** |
Women | 3.7% | 1.5% | 151.3% | 0.1% | 22.9% |
Note: n = 32 countries. CV is the coefficient of variation; significance levels: ** p ≤ 0.05; MW—Mann-Whitney U test [64]. We used nonparametric statistics because the test of normality carried out (here the Shapiro–Wilk test) rejected the null hypothesis of normality. The MW test does not assume a normal distribution of the variables, unlike the analogous one-way analysis of variance and Student’s t-tests [65].
