摘要
应用圆形分布法对贵州省南部地区1212名毛南族、布依族、苗族和汉族发旋角度资料进行统计分析,结果表明发旋集中分布在头顶后正中线附近(r=0.6577,P<0.001),且分布特征无民族、性别和旋向等差别(P>0.05)。
In this paper, we analyzed the angle data of 1212 cases of hair vortexes in the Maonan, Bouyi, Miao and Han nationality by the method of circular statistics. The re-suits showed the hair vortexes had got tendency of concentrate distribution arounding the median line of the back crown of the head (mean nagle was 173.7° , r= 0. 6577, P< 0.001 ), and the diffecences of the peak place of vortexes were not significancy, without distinction of nationality, sex and direction of vortex (P > 0.05).
