Sex determination from calcaneus in Korean using discriminant analysis

The sample consisted of 104 calcanei from modern Korean cadavers, and 10 variables were measured for each. All variables showed statistically significant sexual differences (P < 0.05) and generated a large effect size (Cohen's d > 0.9). The accuracy ranged from 65.4 to 89.4%, the highest accuracy was when all variables were used in the direct method. In dimensional groups, the length dimensional group had the highest accuracy (84.6%), and MINB (body of calcaneus) and MAXL (maximum calcaneal length) could be used as a single measurement. Most Korean females were misclassified as males using the equations of other population groups, and this finding demonstrates the necessity of population-specific equations.
