Ability, interest, gender, and family socioeconomic status of 13,248 tenth-grade participants in Project TALENT were studied as they relate to occupational attainment by using discriminant analysis. Individuals were classified into 12 broad categories reported 11 years after graduation. Accuracy analyses indicated correct classifications significantly above chance for all except the Technical and Sales categories. Within-category classification percentages were higher for all groups except Construction. Five canonical discriminant functions that jointly accounted for 96.8% of the between-groups variance were interpreted. The first 2 accounted for 81.9% of the variance. Function 1 was a general ability function; Function 2 differentiated the categories on the basis of mathematics ability and gender. Functions 3 through 5 accounted for 14.9% of the between-groups variance. Some implications of these findings are discussed.
对“人才计划”中13248名十年级参与者的能力、兴趣、性别和家庭社会经济地位与职业成就的关系进行了研究,采用判别分析方法。个体在毕业后11年被分为12个大类进行报告。准确性分析表明,除技术和销售类别外,所有类别的正确分类显著高于随机水平。除建筑类别外,所有组内分类百分比都更高。解释了五个典型判别函数,它们共同解释了组间方差的96.8%。前两个函数解释了方差的81.9%。函数1是一般能力函数;函数2根据数学能力和性别区分类别。函数3至5解释了组间方差的14.9%。讨论了这些发现的一些含义。
