Correlation (Pearson, Kendall, Spearman) Correlation is a bivariate analysis that measures the strength of association between two variables and the direction of the relationship. In terms of the strength of relationship, the value of the correlation coefficient varies between +1 and -1. A value of ± 1 indicates a perfect degree of association Correlation between two variables indicates that a relationship exists between those variables. In statistics, correlation is a quantitative assessment that measures the strength of that relationship. Learn about the most common type of correlation—Pearson’s correlation coefficient.
