Mann-Whitney U test comparisons (p-values in parentheses) of differences between Mode 1 cores (<i>n</i> = 157), Acheulean (<i>n</i> = 255) and Bose (<i>n</i> = 56) handaxes on the first two Principal Components.

Mann-Whitney U test comparisons (p-values in parentheses) of differences between Mode 1 cores (n = 157), Acheulean (n = 255) and Bose (n = 56) handaxes on the first two Principal Components.针对模式1石器核（Mode 1 cores，n=157）、阿舍利手斧（Acheulean handaxes，n=255）与百色手斧（Bose handaxes，n=56）在前两个主成分（Principal Components）上的差异开展曼-惠特尼U检验（Mann-Whitney U test）比较，检验对应的p值标注于括号内。
