Descriptive and test statistics of significant 3D surface texture (3DST) parameters on facet 9 between Liberian and Taï chimpanzees.

To test the level of significance a combination of the robust Welch–Yuen heteroscedastic omnibus test (WYT), heteroscedastic pairwise comparison test (Dunnett), heteroscedastic rank based test (Cliff) were used. Following Calandra et al. [25] values in bold indicate a significant differences (p ≤ pc ≤ 0.05), no significant difference was detected in case of p > 0.05 and p ≥ pc). U = upper teeth, L = lower teeth, M1 = first molar, M2 = second molar, dp4 = fourth deciduous premolar, N = number of individuals, SD = standard deviation, Ft / ph = test statistics, p = level of significance, nu1 / nu2 / Df = degree of freedom, pl = lower 95% confidence interval, pu = upper 95% confidence interval, pc = critical significance level adjusted for family-wise error.
