Since the regression equation is: y = 30 8x. if SSE= 960, the correlation coefficient is 0.661.
What is the regression equation about?
A regression equation is known to be a tool that is often used in statistics to examine if any relationship exists or not between a given sets of data.
Note that:
SSR=SST-SSE
So the first step is to calculate the R² which is seen as the coefficient of equation. This will be:
= 1 - SSE/SS Total
= 1 - 900/1600
= 1 - 0.5625
= 0.4375
Then, the correlation coefficient will be:
= ✓0.4375
= 0.661
Therefore, Since the regression equation is: y = 30 8x. if sse = 960, the correlation coefficient is 0.661.
