Question about Casio FX-9860G Graphic Calculator
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.

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.
