Question about Casio FX9750GII Graphic Calculator
It is difficult to know exactly WHY it gives you inaccurate values, or does it? I am inclined to believe that you might (just might) have made mistakes entering the data. (A single error in an extreme value will affect the mean).
I would blame the calculator only after I have made certain that I did not make mistakes myself. (That is my way of doing things.)
