Abstract
Discriminant function analysis was employed to test sexual dimorphism and ancestral differences in the basicrania of European Americans and African Americans. The data used was originally collected on crania from the Terry and Bass III Donated Collections, using a three-dimensional digitizer. The data was converted to linear data using the method of Franklin et al. (2005). The results showed that sexual dimorphism and ancestral differences do exist in the cranial base of European and African Americans and individuals can be correctly classified at rates ranging from 75% to 80.4%, depending on the analysis
