This tool applies a standard formula from the relevant domain. The computation is deterministic — given the same inputs, the result is always identical. The formula accounts for the primary variables that determine the output.
r = Σ(x−x̄)(y−ȳ) / √(Σ(x−x̄)² × Σ(y−ȳ)²)The calculation requires: X Values, Y Values. Each parameter contributes to the final result according to the formula above. Accuracy depends on the precision of your input measurements.
