MY TI84 CALCULATOR SHOWS ERROR: ARGUMENT

This is to be expected. A standard deviation of 0 means that all the data points are identical. Asking for the point below which .025 of the data lie is meaningless.

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.

The normalcdf function takes three arguments: the z value, the mean, and the standard deviation. In the "standard" case the mean is 0 and the standard deviation is 1. Thus, try calculating
normalcdf(-.1923, 0, 1) .

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

I want to calculate a standard deviation on BA II plus

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.

1. Press STAT
2. Select EDIT
3. 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)
   
4. 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!)
5. Press STAT
6. Select CALC
7. Select OneVa
8. Select LIST, NAMES, xStat(F2), Press ENTER
9. The calculator provides Max, Min, Mean, Standard Deviation, Sum, Sigma, etc. You will be primarily interested in the Mean and Standard Deviation (sx).

StdDev( {1,2,3,4,5,6,7,8,9,10} )
with your list inside the curly braces.

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