What is spearman rank correlation?

Answer 1

Spearman Rank Correlation is a non-parametric measure of rank correlation, meaning it assesses the statistical dependence between the rankings of two variables. It evaluates how well the relationship between two variables can be described using a monotonic function.

ρ = 1 - \frac{6 \sum d _{i}^{2}}{n ( n ^{2} - 1 )}

where $d_{i}$ is the numerical difference between the two ranks of each paired observation, and $n$ is the total number of observations.
