Rank Correlation
Spearman's Rank Correlation
This graph shows a Spearman rank correlation of 1 and a Pearson correlation coefficient of 0.88. A Spearman correlation of 1 results when the two variables being compared are monotonically related, even if their relationship is not linear. In contrast, this does not give a perfect Pearson correlation.
