胫骨性别分级判别及其与传统方法比较

目的：为验证性别分级判别法在实际应用中的效果及提高胫骨的性别判别率,材料和方法：先抽取126侧胫骨（M68,F58）进行研究,并将其结果作为预计值,另抽取168侧胫骨（M90,F78）进行对比实验,将其结果作为实验值。结果：分级判别法的判别率多因素判别及单因素判别的最高正确判别率预计值分别为89．6％,80．2％和78．6％;实验值分别为84．5％,75．6％和73．2％,讨论：新方法无论在理论预计值上还是在实际应用中较传统方法均有较大提高;实验值较预计值的降低是由于抽样误差造成的。因此,此方法将是人类学及其相关学科研究的更有效的手段。

COMPARISON BETWEEN THE SEXUAL DISCRIMINANT ANALYSIS OF THE TIBIA BY DIFFERENT LEVEL AND THE TRADITIONAL METHODS

Objective:To improve the sexual discrimination method and increase the sexual discrimination correct rate of tibia.Methods:One hundred and twenty six sides of tibiae (male 68,female 58) were measured and calculated by SPSS.Besides,another 168 sides'results were taken as control.Results:The correct rate of the discrimination analysis by different level in estimated value was 89.60%.the highest rates of multifactor and one factor were 80.2% and 78.6%.But in control group,they were 84.5%,75.6% and 73.2%,respectively.Conclusion:Sexual discrimination analysis by different level,is better than that of the traditional methods both in theory and in practice.The differences between the estimated value and the experimental value are derived from the sampling error.So the method of sexual discrimination analysis by different level is more effective in anthropology and other relative fields.
