描述性统计分析是统计分析的第一步，做好这第一步是下面进行正确统计推断的 先决条件。SPSS 的许多模块均可完成描述性分析，但专门为该目的而设计的几 个模块则集中在 Descriptive Statistics 菜单中，最常用的是列在最前面的四 个过程：Frequencies 过程的特色是产生频数表；Descriptives 过程则进行一般 性的统计描述；

Too complex for complete analysis Separation into non-interacting subsystems distorts the results The most important properties are emergent Too organized for statistics Too much underlying structure that distorts the statistics Organized Complexity\(Weinberg) Copyright Nancy Leveson, Sept 1999
