Abstract— Quantitative morphometric measurements with advanced analytical methods are emerging as reliable methods for sex differentiation of skeletal remnants. Aim of present study was to determine the difference in morphometric measurements in male and female skull and to determine the independents predictors and accuracy for sex differentiation using discriminant function analysis. A comparative observational study was conducted using 44 skull of known sex including 24skulls of males and 20 skulls of females. Various morphometric parameters are measured and analyzed using univariate, multivariate and discriminant function analysis. Cranial AP length, Bi Zygomatic diameter, Nasal Height, Nasal width and Mastoid length were found to be significantly higher in male skull. Discriminant function analysis predicted correctly the sex of skull with 79.5% accuracy. Morphometric measurement of cranium can be developed as objective method of sex determination with higher accuracy and repeatability and further enhanced by advanced statistical method like discriminant function analysis.
