Correlation coefficientdoes not clearly indicate the cause-and-effect relationshipbetween the variables, i.e. it cannot be said with certainty that one variable is the cause, and the other is the effect. Whereas, the Regression Analysisclearly indicates the cause-and-effect relationshipbetween the ...
The correlation coefficient also does not describe the slope of the line of best fit; the slope can be determined with theleast squares methodin regression analysis. The Pearson correlation coefficient can’t be used to assess nonlinear associations or those arising from sampled data not subject to...
