Solution 11741: Displaying the Correlation Coefficient (R) and Coefficient of Determination (R^2) on the TI-89 Family, TI-92 Family and Voyage™ 200 Graphing Calculators.
How do I get the TI-89 family, TI-92 family and Voyage 200 graphing calculators to display the correlation coefficient and coefficient of determination?
The correlation coefficient will only be displayed for linear regression calculations (LinReg). The coefficient of determination will be displayed for all polynomial regression calculations (QuadReg, CubicReg, QuartReg).
Please see the TI-89 family, TI-92 family and Voyage 200 guidebooks for additional information.
