R^2 calculation.

Hey, does anybody know a formula to calculate the value of R^2 for a given table of values? I have a table with original data points and another table with points that I have obtained experimentally. Any help is appreciated. Thanks!

If you input those values into a graphing calculator, you can get the R^2 value when you do a regression. Make sure you've chosen the best-fitting regression.

You can calculate the R^2 value using Excel as well.
Plot your points. Insert a trendline. & Click 'Dispay R^2 value.'

Thanks a lot! Though I had to develop another method as this was not so accurate as I thought.
