Coefficient of determination r2 is said to be

WebAnswer The coefficient of determination, R 2 is 0.5057 or 50.57%. This value means that 50.57% of the variation in weight can be explained by height. Remember, for this example we found the correlation value, r, to be 0.711. So, we can now see that r 2 = ( 0.711) 2 = .506 which is the same reported for R-sq in the Minitab output. Try it!
