Here are the capabilities of the Casio calculators.
The screen captures may not look like ones taken from the FX-7400G
plus display but the instructions are accurate.
In stat enter the values in List1 and the frequencies in List2 (if doing paired variable statistics)
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-variable stats or regressions.

Use you knowledge of sample standard deviations and
population standard deviation to select which is relevant to your case.
They are given by xsigma-n and xSigma n-1

How do I get the variance, the standard deviation, and the sample standard deviation in a casio FX-115Es.. Thank you


The variance is the square of the standard variation

TO COMPUTE STANDARD DEVIATION AND 2-VAR STATISTICS.

I assume you know the theory. I will show you the key strokes

for 1-Var statistics
Press [MODE][3:STAT] [1:1-VAR]. You are ready to enter values in the X column.
Enter a number and press [=]. Cursor jumps to second number to enter.
Keep entering numbers and pressing [=] till all numbers are in. Press the [=] key after the last one.
Press [AC] key to clear the screen.
Press [SHIFT] [STAT] (above digit 1.) then [5:Var]. Screen displays the statistical variables 1:n ;2: x bar; 3: x sigma n; 4:x sigma n-1.
Press the number corresponding to the statistical value you want, ex 1:n . The variable appears on screen. Press [=] and it will be displayed.
To display another variable press [SHIFT][STAT][5:Var][ 1,2, 3, or 4] .

To access the sum of squares sigma x^2 and the sum of data sigma x press[SHIFT][STAT][4:SUM] then [1: for sigma x^2] or [2: for sigma x]. Press [SHIFT][STAT][6:MinMax] to access minX and maxX.

For 2-var statistics
To perform 2 variable statistics you press [MODE][3:STAT] and any of the other regression options (except 1:1-Var). A two column template opens where you enter the X and Y values. When finished entering data, press [SHIFT][STAT][5:Var]. to access the different statistics. As I assumed above, you should be able to recognize what each variable means.

How to use that standard deviation on the Casio fx-260solar calculator


  1. Calculator must be in SD mode (standard deviation mode) :Press [MODE] [.]
  2. However, if [FIX] or [SCI] appears on display you must press [MODE][9] first.
  3. Data input always starts with [SHIFT][SAC], to clear the registers of old data.
  4. Type a number and press the [DATA] key, it is the [M+] key at the bottom right of keypad.
After you finish entering the data

Press [SHIFT] [9] (sigma n-1) to get sample standard deviation
Press [SHIFT][8] (sigma n] for the population standard deviation
Press [SHIFT] [7] (xbar) for the mean
Press [SHIFT] [6] (n) for the number of data entries
Press [SHIFT] [5] (capital sigma x) for the sum of values
Press [SHIFT] [4] (capital sigma x to y) for the sum of squares of the values

For additional information you might consider taking a look at the calculator manual

Calculate Variance on Casio FX-83ES Calculator


Hello,
I am happy that you found my solution helpful and even flattered that you copied it in this thread. By doing this, you gave me the opportunity to discover an error in my post. In fact, the calculator does provide a column for the frequency. If you enter nothing in the frequency column, all data items will have their frequency set to 1, by default.

Back to the current subject: How to get the variance (the square of the standard deviation).
When you finish entering your data:
  1. Press the [AC] button to exit the data editor.
  2. Press [****][STAT].
  3. Press [5:Var] to open the statistical result selection screen.
  4. Press [3: xSigma_n] or [4:xSigma_n -1] depending on what you are interested in (population or sample) standard deviation.
  5. The screen echoes the symbol for the value selected (the value displayed on the bottom line may be 0 or an old value from a previous calculation: it is not the value you have just calculated).
  6. Press [=] to display the current value of the SD chosen.
  7. By doing this you are in fact storing it it answer memory.
  8. All you have to do now is to raise it to power 2 by pressing the [x^2] key ( the one above the [HYP] key).
  9. The calculator will display Ans^2.
  10. Press [=] to display the value of the variance.
If you are not interested in the value of the standard deviation, but just want the variance, follow the foregoing procedure until step #5.
While the symbol xSigma_n or xSigma_n-1 is still displayed with the blinking cursor to its right, press the [x^2] key above the [HYP] key. The screen displays say xSigma_n ^2. Press [=] to calculate the variance.

As my motto says, I am always happy to help, but happier still when people show true appreciation.

Hope it helps.

How do i find the variance if i'm given the x


Hello,
Set the [Mode] to [3:STAT]. You are offered the choices
1:1-Var
2:A+BX
3:__+cX^2
etc.
If you want to do 1-Var statistics, you press 1:1-Var. A column template opens where you put the X values. If a value is repeated you enter it several times. (there is no frequency column.)
When you enter all data you press [SHIFT][STAT]

You have several choices among them
4: SUM to get SigmaX^2 and Sigma X
5: VAR to get n, the mean X bar, the sample and population standard deviations
6:MINIMAX to get MinX and MaxX
7: Distr the Distributions.

If you want to perform 2-Var statistics
You press [MODE][STAT] and select one of the Regression models
2:A+BX
3:__+cX^2
etc.
The selection of any of the 7 regression models, opens a two-column template where you enter the X and Y values
When finished press [SHIFT][STAT]
The choices offered are
  1. Type takes you back to select type of statistics to perform
  2. Data To edit the data in the columns
  3. Edit To insert or delete a value
  4. SUM To access the calculated values of SigX^2,SigX,SigY^2,SigY,SigXY,SigX^3, SigX^2Y, SigX^4
  5. Var : To access the calculated values n, Xbar, Sample STD for x, S STD for Y, Pop STD for X, and Pop STD for Y
  6. MinMax : MinX, MinY, MaxX, MaxY
  7. Reg: Gives you the regression coefficients for the particular regression model you want to test.
The mean is represented by X bar.
The variance is the SQUARE of the Standard Deviation.
Hope it helps.

Hello,
Even a smile requires the contraction of about a dozen facial muscles. So here is how you do it (not the smile, the standard deviation).
