is there a way to find R^2 through a “pencil and paper” process?? I know the equation for R^2 for a linear regression. But its the quadratic I need to know about. Please, anyone, help!! You’re performing quadratic regressions on a calculator? I hope the poor thing doesn’t ove...

If you are using Excel, the perhaps the easiest way is to run a linear regression procedure, which will report both R^2 and Adj. R^2 along. The disadvantage of using Excel is that you do not get the steps shown, unlike this adj. R^2 calculator that gives you all the steps of the...
