Table 3. Kruskal-Wallis Z-values for two-tailed pairwise comparisons across the six sets of recent human external auditory exostosis (EAE) frequencies.

With a Bonferroni correction, the medians are significantly different if Z > 2.935. Overall Kruskal-Wallis p < 0.0001 (corrected for ties; χ² = 37.59). Normality (both skewness and kurtosis) rejected at p < 0.0001.
