### Coeficient de determination

Hi there,

To get the coefficient of determination you need to be in STAT mode (press MODE and choose 1 for stat) and then choose 1 for line (it only works for linear data). Type in your coordinate points (type in the x value then press the button next to ENT that says (x,y) and then type in your y value and press ENT. Your screen should then say DATA SET = 1.00.
Enter a few more coordinates.
Then to get your coefficient of determination press ALPHA (the blue green button under 2nd F) and press the ( button (above it in blue you will see r). Press = and there is your coefficient of determination.
