Sex allocation of skeletal material by analysis of the proximal tibia.

In this study we contrasted the confidence with which individuals may be grouped and then reallocated on the basis of a set of measurements from the proximal tibia. The data were derived from 100 Caucasoid (50 male) and 102 Negro (50 male) tibia housed in the R.A. Dart Collection. Multivariate discrimination was effected by means of canonical and stepwise discriminant analyses, whilst probabalistic models were used to allocate individuals. High levels of correct classification (84.62-92%) were matched by high levels of reallocation, suggesting that, in contrast to dental or craniobasal measurements, those of the proximal tibia may be usefully employed to allocate an individual on the basis of sex.
