毕业论文 某高校在校生体测成绩的统计分析 A STATISTICAL ANALYSIS OF COLLEGE STUDENTS THE CERVIX SCORES 摘 要 在现代生活中，随着生活水平的日渐提高，现在大学生的身体素质真是越来越差了，越是学历高的人，身体素质普遍就越差。很多人对身体素质这个词并不陌生。在日常生活中，人们常说，谁谁力气大，谁谁跑的快，或者谁谁很灵活，谁谁耐久力强。实际上这些能力都属于身体素质。身体素质通常指的是人体在肌肉活动中所表现出来的各种能力。一般包括力量、速度、耐力、灵敏和柔韧。 因此，本文通过分析中国农业大学2010年6290名在校生体测成绩数据，利用matlab统计分析理论建立相关模型，研究当前大学生身体素质的真实现状，该研究成果有着非常重要的应用价值。首先利用描述性统计分析方法对体测数据进行初步研究。再利用方差分析对13个学院的学生的身高进行单因素一元方差分析和非参数分析，判断不同学院的学生的身高有无显著性差异。在研究身高和体重的关系时，利用了MATLAN做了回归模型，用一元回归求出身高和体重的函数关系，二元回归求出来身高和体重做自变量，肺活量做因变量的函数关系。判别分析主要是用5999个学生的身高体重等级去判别291个学生的类别。 关键词：体测成绩； 统计分析； MATLAB； 方差分析； 回归分析； 判别分析 ABSTRACT In the modern life, along with the rising of living standards, college students physical quality is worse and worse now, the more highly educated people, physical quality general the worse. A lot of people is no stranger to the word physical quality. In daily life, people often say, so-and-so in strength, who can run fast, or who is very flexible, so-and-so strong endurance. In fact these abilities are physical quality. Physical quality usually refers to the human body in muscle activity of all kinds of ability. Generally includes power, speed, stamina, agility and flexibility. Therefore, through the analysis of China agricultural university in 2010, 6290 students cervix result data, the relevant model is established using MATLAB statistic analysis theory, research the real status of the current college students physical quality, the results of the study has a very important application value. First，use of descriptive statistics analysis method to a preliminary study on the cervix data. Second, analysis of variance on the height of 13 students of the college on a single factor analysis of variance and nonparametric analysis, judge the height of different college students have significant differences. In the study of the relationship between height and weight, use of MATLAN made a regression model, use A regression model to the function relation of height and weigh
