CO OZNACZA SŁOWO SPEARMAN'S RANK-ORDER COEFFICIENT
Definicja słowa Spearman's rank-order coefficient w słowniku
Definicja współczynnika rang Spearmana w słowniku jest statystyką mierzącą stopień, w jakim dwa zbiory dyskretnych danych umieszczają odrębne elementy w tej samej kolejności, podane przez rS = 1 - 6Σ d² / n, gdzie Σ d² jest sumą kwadratów różnic rang pomiędzy dwoma uporządkowaniami i n jest liczbą pozycji w każdym Zwany również: Współczynnik korelacji rang Spearmana.

Review of Progress in Quantitative Nondestructive Evaluation
The Pearson's coefficient is known to be valid for the case of bi-normal distributed
data while the Spearman's rank-order coefficient, derived from non-parametric
statistics, is not limited by this constraint. Spearman's method also shows general
