SOURCE: HOW DO YOU ENTER r2 ON A TEXAS INSTRUMENT CALCULATOR?
Hello,
No need to enter R squared. If it has meaning it will display in the stats variables screen ( 2nd F7 ).
Hope it helps.

Hello,
I am aware that the solution provided below is valid for the CFX/FX-9850G/GB/ but I will supply it. I remain convinced it will help you for your calculator.
In the main menu select [STAT] icon to enter Stat mode and display the
statistical data lists. Use the satistical data lists to input data and
perform statistical calculations. Use the arrows to move the
highlighting around the lists.
Exemple: Enter the following values in List 1
1st line enter 90 [EXE]
2nd line 85 [EXE]
3 79 [EXE]
4 75 [EXE]
5 70 [EXE]
6 68 [EXE]
7 56 [EXE]
When finished you press [F2:Calc], then [F1:1Var] and the statistical results appear on screen.
Title of screen : 1-Variable
x bar =74.7142857
Capital Sigma x= 523
Capita Sigma X squared = 39851
x lower case sigma n = 10.5249945
x lower case sigma n-1= 11.3682934
n = 7
Scroll down with Down arrow to access other data
minX =56
Q1=68
Med =75
Q3=85
Xbar -x lower case sigma n =64.1892911
x bar + x lower case sigma n = 85.2392802
maxX=90
Mod=90
All you have to do now, is to look at the theory you learned and interpret what these values mean.
Hope it helps.

I am sorry but I will have to assume that you know how to enter the data.
Once you enter your data [MENU][STAT], press [F1:Graph], select Gph1,
Gph2, or Gph3. Once the graph of the experimental data is drawn, you
will have access to the diverse regression models. Your choices are
[X:Linear] [Med-Med], [Quadratic :X^2] [Cubic;X^3] [Quartic: X^2].
Press [F6] to scroll right to access the others: [Logarithmic:LOG],
[Exponential :EXP], [Power :Pwr] and [Sinusoidal: Sin]
After you select a model and press [EXE], the screen displays the
equation and its various coefficients. On that same screen, you have a
menu option [F6:Draw]. If you select it, the regression curve will be
drawn on the same screen as your statistical graph. This allows you to
judge if the fit is good. If it is not, you have the option to choose
another model.
The other option [F5:Copy] allows you to save the regression equation in the Y1, Y2, etc. variables.
PS If you do not know how to enter data post a comment to this effect and I will see what I can do to help you.
