Strength of spearman correlation
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 WebApr 11, 2024 · Interpretation: The Pearson correlation coefficient measures the strength and direction of the linear relationship between two variables, ranging from -1 (perfect …
