korrelaatiokertoimilla
Korrelaatiokertoimilla (Finnish) refers to numerical measures used to describe the extent and direction of a linear or monotonic relationship between two variables. The most widely used correlation coefficient is Pearson’s r, which quantifies the strength of a linear association and is defined as the covariance of the variables divided by the product of their standard deviations. Pearson’s r ranges from –1 to +1, where values close to –1 or +1 indicate strong negative or positive linear relationships, respectively, and values near zero suggest little or no linear association.
Spearman’s rank correlation coefficient (Spearman’s ρ) is a non‑parametric measure that evaluates the monotonic relationship between variables
Interpreting correlation coefficients requires consideration of sample size, data distribution, and measurement scale. Correlation does not
