相关系数统计量的功能及其应用探讨——以SPSS为分析工具

相关系数分为简单相关系数、复相关系数和偏相关系数,他们的含义、功能、应用和计算机的实现操作各不相同。尽管相关系数统计量的计算可由多种软件完成,但从操作的简单性、结果的解释性方面看,SPSS、马克威等傻瓜软件应作为首选。选择因变量的影响因素时,我们主张使用偏相关系数,反对使用简单相关系数。

Discussions on the Functions of the Statistics of Correlation Coefficient and its Applications: Taking SPSS as Analysis Tool

Correlation coefficient can be catalogued into simple correlation coefficient, multiple correlation coefficient and partial correlation coefficient. Their meanings, functions, applications and the computer operations are different from each another. Although the calculation of statistics of correlation coefficient can be executed by different software, yet from the simplicity of operation and the explanatory of results, such fool software as SPSS, MARKWAY should be the best choice. When choosing the impact factors of variation, it's advocated that partial correlation is used, rather than simple correlation.
