Metric data on 200 sacra of known sex, age and race are analyzed to determine the usefulness of conventional observations for determining sex in this bone. Results of the univariate analysis show that significant sex differences in the sacrum involve primarily the top portion of the bone for both whites and blacks. However, measurements of curvature are important sex differences in the sample of blacks. A new index relating the S1 body to sacral breadth is proposed as more useful in classifying the bones by sex than indices involving other measurements. Discriminant analysis shows that the sample of whites can be analyzed significantly better by this method than by using an index. The choice of univariate or multivariate method must depend on the condition of the bone, and will be influenced to some extent by the race from which the sample is drawn.
对200具已知性别、年龄和种族的骶骨的测量数据进行分析，以确定常规观察结果在通过该骨骼确定性别方面的实用性。单变量分析结果表明，白人和黑人的骶骨在性别上的显著差异主要涉及骨骼的顶部。然而，在黑人样本中，曲率测量是重要的性别差异。提出了一种将第一骶椎体与骶骨宽度相关联的新指数，在按性别对骨骼进行分类方面比涉及其他测量的指数更有用。判别分析表明，与使用指数相比，用这种方法对白人群体样本进行分析的效果要好得多。选择单变量法还是多变量法必须取决于骨骼的状况，并且在一定程度上会受到所抽取样本的种族的影响。
