Table 10. Von Mises strain magnitudes: Human vs. Chimpanzee.

Results of pairwise comparisons (Mann-Whitney U-test) of von Mises strain magnitudes at the 14 locations examined between CHIMPED variants of human FEMs and data on chimpanzees from Smith et al. (2015b). Because of small sample sizes, the “exact” variant of p is reported (Mundry & Fischer, 1998). Comparisons that yielded significant results following Holm-Bonferroni correction are marked by asterisks. When significant, humans were found to exhibit the higher average value, with the exception of locations 13 and 14, where humans were found to exhibit significantly lower strain magnitudes.
