SPSS发硒和血硒的含量的相关性分析.docx

1、SPSS发硒和血硒的含量的相关性分析关于十个人发硒和血硒含量相关性的分析报告一、问题提出调查了10个人的发硒和血硒的含量，数据如图1，分析两者之间的相关性图1 原始数据二、数据分析1.激活数据管理窗口（如图2），定义变量，发硒为X，血硒为Y，建立数据库（如图3）图2 导入数据图3 定义后数据2.AnalyzeCorrelateBivariate.弹出Bivariate Correlation对话框（如图4），在变量列表中选X、Y，选中Pearson（相关系数），Two-tailed（双侧检验）（如图5）图4 图53.点击Options，弹出Bivariate Correlation：Optio

2、ns对话框，选择Means and standard deviations和Cross-product deviations and covariances项，点击Continue返回，点击OK图6得到的结果如下Descriptive Statistics均值标准差样本量X75.4012.29510Y10.803.32710CorrelationsXYX相关系数1.872*显著性水平.001交叉乘积的例数1.360E3320.800协方差151.15635.644样本量1010Y相关系数.872*1显著性水平.001交叉乘积的例数320.80099.600协方差35.64411.067样本量1
