SPSS统计分析(八)探索性分析
SPSS Statistical Analysis (8) Exploratory Analysis
探索分析是一种在对资料的性质、分布特点等完全不清楚的情况下,对变量进行更深入研究的描述性统计方法。
Exploratory analysis is a descriptive statistical method that conducts more in-depth research on variables when the nature and distribution characteristics of the data are completely unclear.
探索性分析提供了很多关于数据的概括分析和图标直观描述的方法,不仅对个案数据有效,而且可以针对分组个案。在输出常用描述性统计量的基础之上,探索性分析增加了有关数据详细分布特征的文字和图形描述,如茎叶图、箱图等,更加详细、完整,还可以提供正态分布检验和方差齐性检验,有助于用户制定进一步分析的方案。
Exploratory analysis provides many methods for generalized analysis and graphical representation of data, not only for case data, but also for grouped cases. On the basis of outputting common descriptive statistics, exploratory analysis adds text and graphic descriptions about the detailed distribution characteristics of the data, such as stem-and-leaf plots, box plots, etc., which are more detailed and complete, and can also provide normal distribution test and The homogeneity of variance test helps users formulate plans for further analysis.
