Spearman分析:揭秘等级相关 Spearman等级相关系数(Spearman's rank order correlation coefficient)是一种用于定序尺度(ordinal scale)数据的相关分析方法。它特别适用于两个变量都是等级尺度的情况,目的是衡量两组等级之间的一致性程度。 应用场景: 两个人对N台笔记本电脑的印象分数进行等级评定。 一个人对N台笔记本电脑...
An online Spearman's Rho (correlation coefficient) calculator (offers scatter diagram, full details of the calculations performed, etc).
相对应的spearman correlation对异常值不敏感,因为它是属于rank test,具体见下面介绍。 spearman correlation coefficient(斯皮尔曼相关性系数-p) 通常也叫斯皮尔曼秩相关系数。 “秩”,可以理解成就是一种顺序或者排序,那么它就是根据原始数据的排序位置进行求解,而不是直接是用x,y的值进行求解(因此对异常值不敏感...
Interpreting the Results of the Spearman Correlation Coefficient Test Since the correlation (0.367) isn't 0.80 or greater, we cannot conclude there is a correlation between smoking and hypertension in these ten smokers.

needed for this test to be statistically reliable. - A strong correlation indicates that there is a link between the two factors but not that one causes the other. - For example there may be a strong correlation between the incidence of ...
When data is not normally distributed or when the presence of outliers gives a distorted picture of the association between two random variables, Spearman’s rank correlation is a non-parametric test that can be used instead of the Pearson’s correlation coefficient. ...
