### How to calculate standard deviation

Hi there,

My name is adieh. Hav a great day.

Here are the tips on how to calculate standard deviation using a graphic calculator:

2. Push the catalog button and scroll through the applications until you find "stdDev(". Place the arrow next to it and press enter.

3.Type the word "list1" into the open parenthesis. After you have put that in, close the parenthesis so you calculator doesn't show an error message.

4. Press the enter button. The calculator has done the calculations and you now have the standard deviation of your data set.

Note:
Using 1-var stats in the stats/editor screen will also give you the standard deviation. Using that function will also give you other information associated with your data set.

Hope it helps.

Thank you for using fixya.

### How do you find standard deviation on the calculator?

Press 2nd [CSR] (shift-7) to clear the statistical registers. Use the Sigma+ key (just above STO) to enter data points. Use 2nd [Sigma-] to remove erroneous data points. Use 2nd [sigma x n] (shift-divide) to compute the population standard deviation, or 2nd [sigma x n-1] (just to the left of the previous key) to compute the sample standard deviation.

### 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.

### Does this calculator comes with a standard deviation or population standard deviation button

Yes. The sample standard deviation is 2nd [sigma x n-1] and the population standard deviation is 2nd [sigma x n].

### Is there a formula for standard deviation problems

Hello,
Of course there are formulas for those calculations. You find them in books on statistics. Do not worry, the calculator has been programmed to use them. All you have to do is learn how to get the calculator to give you the results.

If you still want to see the formulas with your very eyes, I suggest you go to the local library, ask a math teacher, an accountant, or launch a Google search for them.
Hope it helps.
