WebJun 10, 2024 · Spearman's rank correlation, or Spearman's Rho, is a correlational analysis that is generally used if two conditions are met: The variables that are being analyzed are ranked or ordinal variables ... WebCorrelation. The Pearson correlation coefficient, r, can take on values between -1 and 1. The further away r is from zero, the stronger the linear relationship between the two variables. The sign of r corresponds to the direction of the relationship. If r is positive, then as one variable increases, the other tends to increase.
