http://www.sthda.com/english/wiki/correlation-test-between-two-variables-in-r WebSpearman's rank correlation coefficient takes values in [ − 1, 1]. 0 means no correlation (in this sense, of course), positive values of this coefficient indicate positive association and similarly for negative values. Say you calculate a confidence interval for this coefficient and you get I = ( 0.7, 0.9).
