Correlation coefficient on ti 84.

1 Answer. The regression equation is there to tell you the direction of the correlation. If you know r2 = 0.64 r 2 = 0.64, then r = ±0.8 r = ± 0.8. To decide on whether the correlation is positive or negative you should look at the slope of the regression line. Since the slope is negative, r = −0.8 r = − 0.8.The correlation coefficient r=.8 is a measure of agreement between the x and y values (± are the best possible values), and r is the percentage of variance accounted for in the model. To get the correlation output, you must set the function DiagnosticOn to the on position. This should be Step 2: Find the Coefficient of Variation. Next, press Stat and then scroll over to the right and press CALC. Then press 1-Var Stats. In the new screen that appears, press Enter.
