Anthropometric Study on the Prosopic Index of Adult Ogoni Tribe
Abstract
This prospective study is aimed at determining the prosopic index of adults from Ogoni. Comparing the prosopic index of males and females, and also comparing the mean prosopic index of Ogoni adults to that of other ethnic groups in Nigeria. A total of 400 volunteer subjects were used for the study (200 males and 200 females). Subjects were purely from Ogoni. Their age ranged from 15-30 years. Their maximum facial length and maximum facial width were measured using a venier caliper and prosopic index calculated by dividing the maximum facial length by maximum facial width and multiplying the result by 100. Theresult showed that the mean prosopic index of Ogonifemale is 80.27 and that of Ogoni is 71.31. Using the z-test to compare the two means, there was a significant difference between the mean of prosopic index of Ogoni males and that of Ogoni females (p<0.05). Theprosopic index of Ogoni males fall under the theeuryprosopic group and the Ogoni females fall under the hypereuryprosopicgroup. This study is therefore recommended in anthropological studies.
