The correlations of the 20 main cranial dimensions, in 2 series of 500 male and 500 female subjects are often higher in man than in the women. This result confirms Schreider's former statement. Through partial correlations, we keep constant the two main sexual characteristics of the skull (weight and volume) : the sexual differences of partial correlation are then in equal number in each sex, Schreider's hypothesis being thus confirmed : sexual dimorphism is partly genetical and related to sex.
在两组各500名男性和500名女性受试者中,20项主要颅骨尺寸的相关性通常男性高于女性。这一结果证实了施赖德之前的说法。通过偏相关性分析,我们保持颅骨的两个主要性别特征(重量和体积)不变:此时两性的偏相关性性别差异数量相等,从而证实了施赖德的假设:性别二态性部分是由基因决定的,且与性别有关。
