Give the largest value rank 1, the second largest value rank 2, etc. Step 2:Calculate the correlation coefficient of the ranked data so So Spearman’s rank correlation coefficient rS = Note: This value represents NOTE: When the data is ranked, you could give the smallest value rank ...
Spearman Rank Correlation Coefficient is a non-parametric measure of correlation, using ranks to calculate the correlation. Spearman Rank Correlation Coefficient uses ranks to calculate correlation. Whenever we are interested to know if two variables are related to each other, we use a statistical ...
Pearson相关系数和Spearman秩相关系数介绍
rs=1−0.559rs=1−0.559 rs=0.441rs=0.441 Output As a result, for the given data, the Spearman's rank correlation coefficient is 0.441, indicating a moderately positive correlation between X and Y. Example 2 Let us take another example to understand how to calculate the Spearman's rank co...
