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).

Hi,

A 6ya expert can help you resolve that issue over the phone in a minute or two.

Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

The service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

Good luck!

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.

The standard deviation is a measure on the variability of a number set from its average. Since all numbers in your set are the same, there is no variation from its average, and the standard deviation is 0.

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.

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

Jill. She scored two standard deviations above the mean, while he only scored one-and-a-half standard deviations above the mean.

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+

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.

1. Put the data into a list.

2. OneVar list will produce a screenful (and more) of one-variable statistics.

OneVar is available through the STAT CALC menu. "list" in step 2 is the name of the list created in step 1.
