• Proper fractions (with or without ?) ? decimal numbers
• Irrational numbers (square roots, fractions made using square
roots) ? decimal numbers

• In the following cases, calculation results may be displayed
using r:
• Arithmetic operations and memory calculations
• Trigonometric calculations
• In trigonometric calculations, when
entering values such as those in
the table to the right, results may be
shown using r.
• Calculation results may extend off
the edges of the screen. You can
see those parts by pressing l
or r (depending on whether the left or right portion is

How do I use the standard deviation function?


  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.
