Background: Determination of biological sex is one of the most important determinations to be made from human remains and is an essential first step in the development of the biological profile in forensics, anthropology and bioarchaeology. The aim of this study was to determine whether sexing of unknown adult human tibia bones can be done by applying values of morphometric parameters and formulae generated by present study on adult human tibia bones of known sex and to find out the best parameters for sex determination.
Methods: Various metric measurements were recorded using osteo metric board, measuring tape, non elastic thread, sliding calipers and vernier calipers on adult human Tibia bones.
Results: Sex was correctly estimated by using direct stepwise discriminant analysis for the tibia 95.6% of males and 89.5 % of females with a total accuracy of 93.5%.
Conclusions: Present study exhibited better classification accuracy for multiple variables than those of single variables. In the tibia, the most discriminating variable in stepwise analysis are Mid shaft circumference and Circumference of upper end.
