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. Pearson = +1, Spearman = +1 WebCorrelation Pearson's correlation coefficient (r) Pearson's correlation coefficient (r) is a statistic that quantifies the relationship between X and Y in unit-free terms. The closer the correlation coefficient is to +1 or -1, the better the two variables "keep in step."
