Am trying to calculate corelation on a Casio fx-9750GII,

Press Menu.
Use arrows to highlight STAT icon and press EXE.
Enter your data in two lists (x-values in L1, Y-values in L2)
Press F2 to activate the CALC Tab at the bottom of screen.


This is what you see.

This is what you will see: the TABs at the bottom of screen.
Each tab corresponds to a regression moam trying to calculate corelation on a Casio - 8_1_2011_10_38_52_am.jpgtic, etc.

If you press F3:X^2, you get the following

You see the parameters of the regression equation, the coefficient of determination r^2, and the Mean Square error. No correlation coefficient is defined for this regression model.
For other models like linear, logarithmic, power and exponential am trying to calculate corelation on a Casio - 8_1_2011_10_44_16_am.jpgation coefficient is defined and is thus displayed with the regression equation. It is the r-value.
