在SPSS中,选择Analyze—Correlate—Bivariate。 将Score1和Score2拖入Variables,选择Spearman作为Correlation Coefficients,并设置Test of Significance为Two-tailed。 点击OK。 查看Correlations表,从中可以看出Score1和Score2之间的相关性是否显著(小于0.01),以及Spearman相关系数(如0.766)。0 0 发表评论 发表 作者最近动态 ...
Spearman's rank correlation coefficient [¦spir·mənz ¦raŋk ‚kär·ə′lā·shən ‚kō·ə‚fish·ənt] (statistics) A statistic used as a measure of correlation in nonparametric statistics when the data are in ordinal form; a product moment correlation coefficient. Al...
Graph of significance levels for Spearman's Rank correlation coefficients using Student'stdistribution The fact two variables correlate cannot prove anything - only further research can actually prove that one thing affects the other. Data reliability is related to the size of the sample. The more ...

Two commonly used correlation coefficients are the Pearson Linear Correlation Coefficient (PLCC) [68] and the Spearman Rank Order Correlation Coefficient (SROCC) [69]. Both are widely used in assessing the performance of IQA models for natural images [29,37,70]. They have recently been used ...
Symbolically, Spearman’s rank correlation coefficient is denoted by rs. It is given by the following formula: rs= 1- (6∑di2)/ (n (n2-1)) *Heredirepresents the difference in the ranks given to the values of the variable for each item of the particular data ...
Like all correlation coefficients, Spearman's rho measuresthe strength of association between two variables. ... All bivariate correlation analyses express the strength of association between two variables in a single value between -1 and +1. This value is called the correlation coefficient. ...
