Difference between correlation and regression-

  • Whereas coefficient is a measure of degree pf co variability between x and y the objective of regression is to find out the nature of relationship between the variables.
  • Correlation is merely a tool of ascertaining the degree of relationship between two variables and we can not say that one variable is the cause another effect.
  • There may be nonsense correlation between two variables which is purely due to chance and has no practical relevance there is nothing like nonsense regression,
  • Correlation coefficient is independent of change of scale and origin regression coefficients are independent of change of scale but not of origin.
