The present study was conducted in Department of Anatomy, MM institute of medical sciences &
research, Mullana (Ambala), on 800 Haryanvi adults comprising of 400 males and 400 females. Prior
informed written consent was obtained from subjects. Inclusion and exclusion criteria for the study were
predefined. Four measurements, maximum head length, maximum head breadth, morphological facial
length and bigonial diameter were taken by using standard anthropometric instruments. The purpose of
study was to determine the sex from these cephalometric parameters by discriminant function analysis.
The results showed that all cephalometric parameters (mean) are more in male than female. Discriminant
function analysis revealed that the cephalometric parameters correctly classified the sex with an
accuracy of 77.5%. (76.3% males & 78.8 % females). Cross validation using "Leave one out method"
prove that the model is fairly reliable with 77.3% (76% males and 78.5% females) cases correctly
classified.
