Formula Used

This calculator uses the following **tie-corrected** formula for Spearman's Rho:

ρ = (n³ - n - 6Σd²) / √( (n³ - n - Tₓ) * (n³ - n - Tᵧ) )

Where:
n = The number of data pairs.
d = The difference between the ranks of corresponding values.
Tₓ, Tᵧ = Tie correction factors for each variable, calculated as Σ(t³ - t) where t is the number of tied observations.
