Group analysis using the metric measurements of Korean skulls

The metric parameters including Martin's(#41, 43, 44, 45, 46, 51, 52, 53) and non- Martin's parameters(nasion-occipital length, glabella-occipital length, nasion-inion length, glabella-lambda length, basion-nasion length, biauricular breadth, biasterion breadth, porion-bregma height, porion-apex height, frontal arc, frontal chord, parietal arc, parietal chord, occipital arc, occipital chord, mastoid height, mastoid width, basion-prosthion length, internal palate length, internal palate breadth, external palate length, external palate breadth) were measured on 61 Korean skulls(M 47, F14) with cephalometry(GPM Co., Swiss) and calipers(GPM Co., Swiss, Mitutoyo Co, Japan). Using the metric data of 35 parameteres, the statistic procedure(descriptive statistics, t-test, paired t-test, discrimination process, group analysis) was performed. Among those parameters, 28 parameters have the statistic significance in group analysis. The 2 clustering was most appropriate.ope
