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.

Here are the capabilities of the calculator.

In stat enter the values in List1 and the frequencies in List2

Press the key corresponding to the CALC tab

Press the 1-var tab and you get the results as seen on the screen with title 1-variable.

Other screens show some two-varaible stats or regressions.

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.)

I just posted an answer to a question, and I believe it answers yours and a bit more.

They are in chronological sequence. If not just rearrange the sequence.

- Arrange you data in ascending order
- Determine the frequency of each datum (for un-grouped data)
- Turn Calculator ON
- Press the MENU key
- Highlight STAT icon and press EXE
- Enter the data item in list1 and frequency in list2
- When finished entering data press F1:Graph
- Select Graph1, Graph2 or Graph3 or SET to fine tune
- Select the Type of graph (Histogram)
- Select the lowest boundary of the first class (to align)
- Set the class width
- Press EXE to draw.

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.

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

Press F6:SET

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.

List2 is now the frequency list.

Press EXE to perform stats.

See that n=19.

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][).

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.
