Four different Parameters of ulnae were studied for making two groups and multivariate analysis of ulnae done for sex determination. SPSS (Sum of products and Sum of Squares) is used for applying multivariate linear discriminant analysis and a discriminant functional score is obtained. Any ulna falling on the male side of the sectioning point will be categorized as male ulna while that falling on female side of sectioning point will be categorized as female ulna.
