摘要 本文致力于对主成分分析在大学生综合评价中的应用研究。 应用SPSS软件做主成分分析，对随机抽取的20名大学生在校的思想品德、专业知识能力、英语水平，体育、专业技能、计算机成绩等多项指标进行分析。根据分析结果，对调查指标累计贡献率达到85%以上，提出了5个反映大学生综合素质评价的主成分及线性组合。通过线性组合可以计算出个主成分的得分，并对学生进行综合评价，对其结果与学生自身发展相联系。大学生在校发展会影响其毕业后所从事的工作的实际表现，表明运用主成分分析对大学生进行综合评价具有科学性和实用性，对大学生的发展素质具有深远意义。比传统的按照学生学习成绩总分相加排列名次的综合评价更具有公平性、合理性。主成分分析为大学生综合评价提供了有效的理论依据。74900

This paper is dedicated to the application of principal component analysis in college students' comprehensive evaluation research。
Family composition analysis using SPSS software, the random 20 college students in the school of thought moral character, professional knowledge, ability, English level, physical education, professional skills, computer performance, and other indicators are analyzed。 According to the results of the analysis on the index of the cumulative contribution rate of 85% or more, puts forward five reflects the college students' comprehensive quality evaluation of the main components and linear combination。 Through the linear combination of a principal component scores can be calculated, and the student to carry on the comprehensive evaluation, the results associated with students' own development。 After graduating from college students in the school development will affect its actual performance of the work, showed that using the principal component analysis to comprehensive evaluation of college students has the scientific nature and the usability, quality has profound significance to the development of college students。 Than traditional according to students' learning achievement scores together to arrange comprehensive evaluation is more in the position in the fairness and rationality。 Principal component analysis comprehensive evaluation provides effective theoretical basis for college students。
