This study examines whether sex determination based on morphological traits in the os coxae is impacted by racial quantitative variation. Nineteen traits were evaluated independently by two observers in 876 os coxae. Chi-square test was used on a random sample of 400 individuals to assess whether the distribution of correct sex assessment varied for white and black individuals based on each trait individually and all 19 traits collectively, as well as on inter-observer agreement in correct sex assessment. Results indicate that accuracy of sex assessment varied between white and black individuals in certain individual traits; however, accuracy was not impacted when all traits were considered together. Furthermore, traits that showed significant variation in correct sex assessment between races generally were not related to size, but instead were "discrete." Finally, analyses of inter-observer variation suggest that disparities in sex assessment for some traits may be related to differences in trait interpretation between observers rather than morphological dissimilarities between races.
本研究考察了基于髋骨形态特征的性别判定是否受到种族数量变异的影响。两名观察者对876块髋骨中的19个特征进行了独立评估。对400名个体的随机样本进行卡方检验，以评估基于每个单独特征以及所有19个特征综合考量的情况下，白人和黑人个体正确性别评估的分布是否存在差异，同时也评估了观察者之间在正确性别评估方面的一致性。结果表明，在某些个体特征上，白人和黑人个体的性别评估准确性存在差异；然而，当综合考虑所有特征时，准确性并未受到影响。此外，在不同种族间正确性别评估显示出显著差异的特征通常与大小无关，而是“离散的”。最后，对观察者间差异的分析表明，某些特征在性别评估上的差异可能与观察者之间对特征的解读差异有关，而非种族间的形态差异。
