How to find correlation coefficient from regression equation

If we have one independent variable, then the given regression coefficient β = Pearson's r. This is not correct. A simple argument is that regression coefficients are not bounded between [-1,1]

Correlation

Now, first, calculate the intercept and slope for the regression. Calculation of Intercept is as follows, a = ( 350 * 120,834 ) – ( 850 * 49,553 ) / 6 * 120,834 – (850) 2 a = 68.63 Calculation of Slope is as follows, b = (6 * 49,553) – (850
