The "normal" way is an anomaly in mathematical notation.

Think of the square of sine of x. It's normally written as sin^2(x) when it actually means (sin(x))^2. Enter the powers of trig functions as in the second form of the previous sentence, and you should have no problems.

If you still have problems, please feel free to respond to this post and give an example.

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.)

There is no such thing as turning the frequency on on the Casio calculators. Just enter your data in lists. Choose one List where you put the frequency information. When you want to GRAPH or perform CALCulations you have a TAB labeled SET corresponding to key F6:SET. When you press F6, a new screen open where you assign the list to the variables.
Here are a few screen captures to help you.

k24674_68.jpg

Press F2:CALC (or F1 Graph). The Tab SET appears at the bottom of screen

k24674_69.jpg

Press F6:SET
k24674_70.jpg
Higlight the line 1-Var Freq (or 2-Var Freq). The bottom of screen shows F1:1 and F2:LIST. If frequencies are not equal to 1, press F2:LIST to assign the frequency list. I entered 2.

k24674_71.jpg

List2 is now the frequency list.

You have two buttons to calculate powers: The [x^2] calculates the square of a number while the [caret ^] key allows you to calculate any power, be it with integer, fraction or negative exponent.
Both keys are next to one another, one below OPTN and the other below the VARS key.
To calculate roots, you have the square root [SHIFT][x^2] the xroot key [SHIFT] [caret ^] , the CUBE root [SHIFT] [(] , and the inverse key [SHIFT][).

In the leftmost column of key, below [X,theta,T] and above digit key 7 is a key marked with [a b/c]. That is the one to use to enter fractions.
Tu use it, type in numerator, press [a b/c] then type in the denominator. If you want to enter a mixed fraction, use the key as follows

Sorry if post is too long. Skim through it to find the inverse of a matrix in part at the end:Part E

Note: Matrix must be square (nXn) and non singular (its determinant not equal to zero)

A. Define a matrix (Create it)

  1. Turn calculator ON.
  2. Press Menu,select the MAT icon and press [EXE]
  3. You see a list of possible matrix labels (A, B, C,D,E,F)
  4. All that have not been created have a "none" to their right
  5. Highlight a matrix name and press the right arrow. Where there was "none" , you have a template 0x0.
  6. That is where you specify the dimensions (mxn). example. 2x2
  7. Enter the first dimension and press [EXE]
  8. Enter the 2nd dimension and press [EXE]
  9. A matrix template opens where you enter the coefficients left to right and up down.
  10. After each coefficient press [EXE]. Cursor moves to the next coefficient, etc.
At the bottom of the screen you have 3 menus for Row and column manipulations. But those will have to wait for now.
Press [SHIFT][QUIT] to return to the list of matrices to create new ones

B Operations on matrices
Once you have one matrix, you can do operations on it: Calculate the determinant (if matrix is square), calculate its inverse, transpose, augment it, fill it, etc..
  1. These operations are accessed as follows.
  2. Quit the matrix editor by pressing [Menu] and selecting the [Run] application.
  3. Press [OPTN][F2:MAT]
  4. You have the menus Mat,M(atrix)->L(ist), Det(erminant), Trn (transpose), Aug(ment) ->, Iden(tity),Dim(ension) Fill
Example : calculate the determinant of a matrix A (already defined).
  1. You press the [OPTN][F2:MAT] key sequence (just above)
  2. Press [F3:Det]; the command det is displayed on screen.
  3. Press [F1:Mat] the identifier Mat is displayed.
  4. Press [ALPHA] A; screen display det Mat A.
  5. Press [EXE] to get the value of the determinant.
C. Square of Matrix A
[OPTN][F2:MAT] (MAT) [Alpha] A ^2 [EXE]

D. Product of two compatible matrices MatAXMatB

[OPTN][F2:MAT] (MAT) [Alpha] A [*] (MAT) [ALPHA] B [EXE]

k24674_10.jpg

Part E Invert a (square, non singular) matrix that was already defined.

Press [OPTN] [F2:Mat] to open a screen similar to the one in capture above
Press [F1:Mat] to have identifier Mat displayed.
Enter the name of the matrix by pressing [ALPHA] A, for example.
Press [SHIFT] [ ) ] activate the (x^-1) key.

This is what you might see (with parentheses and without).

Once the angle unit is correctly set,
  1. Press the function keys [SIN], [COS], [TAN]
  2. Depending on what function you pressed, the command sin( or cos( or tan( is displayed.
  3. Type in the angle value,
  4. close the right parenthesis and

By definition, a fraction is a number that is represented by the ratio of two integers (whole numbers). However, any value in radians is bound to be approximate because the radian unit is intrinsically linked to the value of pi. Ans as you well know, pi is an irrational number: a real number that cannot be represented by a fraction. Does it make sense to try to cast it into a form that it cannot have?

However, if you truncate an irrational number and keep only a limited number of digits in its decimal representation, then that approximate representation can of course be represented by a fraction. To effect that conversion, press the [FD] key to the right of the [a b/c] key.

If the number of display symbols to represent the fraction exceeds the limits of the screen then the calculator will ignore the command. It will not comply, because it cannot comply.
Some decimal representations already displayed as results can be converted, other cannot be.
