SPSS
1.什么是SPSS
SPSS,统计产品与服务解决方案软件。最初软件全称为“社会科学统计软件包”(SolutionsStatistical Package for the Social Sciences),但是随着SPSS产品服务领域的扩大和服务深度的增加,已于2000年正式将英文全称更改为“统计产品与服务解决方案”,标志着SPSS的战略方向正在做出重大调整。SPSS为IBM公司推出的一系列用于统计学分析运算、数据挖掘、预测分析和决策支持任务的软件产品及相关服务的总称SPSS,有Windows和Mac OS X等版本。
1984年SPSS总部首先推出了世界上第一个统计分析软件微机版本SPSS/PC+,开创了SPSS微机系列产品的开发方向,极大地扩充了它的应用范围,并使其能很快地应用于自然科学、技术科学、社会科学的各个领域。
SPSS是世界上最早的统计分析软件,由美国斯坦福大学的三位研究生Norman H. Nie、C. Hadlai (Tex) Hull 和 Dale H. Bent于1968年研究开发成功,同时成立了SPSS公司,并于1975年成立法人组织、在芝加哥组建了SPSS总部。
