Key Takeaways
Spearman's rank correlation coefficient is a statistical measure used to determine the strength of the relationship between two variables. It is a non-parametric test that measures the monotonic relationship between two variables. The coefficient ranges from -1 to 1, with -1 indicating a perfect negative correlation, 1 indicating a perfect positive correlation, and 0 indicating no correlation. It is commonly used when the relationship between two variables is not well-represented by a linear model.
