Correlation (Pearson, Kendall, Spearman) - Statistics Solutions. Correlation is a bivariate analysis that measures the strengths of association between two variables.
In statistics, the value of the correlation coefficient varies between +1 and -1. When the value of the correlation coefficient lies around ± 1, then it is said to be a perfect degree of association between the two variables. As the correlation coefficient value goes towards 0, the relationship between the two variables will be weaker. Encyclopedia of Psychology. Correlation Method in Psychology.
