  1. The Kruskal–Wallis test evaluate the significance of TCSP index differences within geographical regions, whereas the Wilcoxon pairwise comparisons evaluate the significance of differences between all pair of projectile point types within each region.
  2. Values in bold indicates significant differences and values in italics marginally significant differences.
