Question about Texas Instruments TI-30 XIIS Calculator

Re: Standard deviation

What is the standard deviation of the value .252

Posted on Apr 20, 2008

Re: Standard deviation

StdDev( {1,2,3,4,5,6,7,8,9,10} )

with your list inside the curly braces.

SOURCE: standard deviation

Enter the first number, 1.

Hit the σ+ (Sigma+) key. ( n=1 will appear in the window)

Enter the second number, 1.

Hit the σ+ (Sigma+) key. (n=2 will appear in the window)

. . . . .

Enter the last number, 7.

Hit the σ+ (Sigma+) key. (n=7 will appear in the window)

Hit 2nd x2 (by hitting the 2nd key you are actually selecting the x-bar written above the key.) This gives you the mean.

Hit 2nd sqrt(x). This gives you the sample standard deviation which we will use in class.

Make sure you turn your calculator off and on for new data sets.

I want to calculate a standard deviation on BA II plus

If you mean the standard deviation, there are two shifted keys on the third row marked with a lower-case Greek sigma. sigma_xn is the population standard deviation and sigma_xn-1 is the sample 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:

1. Turn on your graphing calculator, go to the stats/editor screen and enter your data set into list1. Once this is done, return to your home page by hitting the home button.

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.

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

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.

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

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.

Press 2ND [CSR] to clear the stat data.

For each data point, enter the number followed by SIGMA+

If you have grouped data, enter the number followed by 2ND [FRQ] followed by the frequency then SIGMA+

Press 2ND [sigma x n] for the population standard deviation or 2ND [sigma x n-1] for the sample standard deviation.

For each data point, enter the number followed by SIGMA+

Texas Instruments TI-86 Statistics How-To Information
The following instructions should allow you to calculate the mean and standard deviation using a TI-86 calculator.

- Press STAT
- Select EDIT
- Enter data into a list: [2.32 ENTER 2.43 ENTER 2.39 ENTER, etc.] Continue until all data have been entered. (use arrows keys to go to the y value, if any)
- EXIT until you reach the main ("blank") screen. (If you try to calculate while you're in the data menu, it thinks you're still trying to enter data!)
- Press STAT
- Select CALC
- Select OneVa
- Select LIST, NAMES, xStat(F2), Press ENTER
- The calculator provides Max, Min, Mean, Standard Deviation, Sum, Sigma, etc. You will be primarily interested in the Mean and Standard Deviation (sx).

This calc will do standard deviations. In the manual it is on page 2 and also on page 40.
