  Therefore, testing for the significance of the slope (b), is equivalent to testing for the correlation coefficient (r). 
  Moreover, the correlation coefficient, r, is equal to the standardized betacoefficient. 
  The multiple correlation coefficient, R, is equal to the product moment correlation, r, that would be calculated if the observed values were correlated with the values computed from the regression equation.
