WebThe Pearson and Spearman correlation coefficients can range in value from −1 to +1. For the Pearson correlation coefficient to be +1, when one variable increases then the other variable increases by a consistent amount. This relationship forms a perfect line. The Spearman correlation coefficient is also +1 in this case. subway interview questionsIn statistics, Spearman's rank correlation coefficient or Spearman's ρ, named after Charles Spearman and often denoted by the Greek letter $${\displaystyle \rho }$$ (rho) or as $${\displaystyle r_{s}}$$, is a nonparametric measure of rank correlation (statistical dependence between the rankings of two variables). It … See more The Spearman correlation coefficient is defined as the Pearson correlation coefficient between the rank variables.
