**Getting the StandardDeviation from your calculator:**

I have used the following data set to get the mean with

several different calculators.

1, 1, 1, 4, 7, 7, 7���

standard deviation = 3

Current Calculators that I have in my office:

- Casio fx-115MS
- Casio FX 115 ES
- TI-30Xa
- Ti-30XIIs
- TI-36x
- TI-83, TI-83Plus
- TI-89

There are hundreds of calculators on the market that find

the standard deviation.� If you do not

have one of these calculators, you have several options.

- Look

at the manual for your calculator. - Go to

Google and type �standard deviation with __________ calculator�.

**Casio fx-115MS**

- Click on the Mode button twice until you see

�SD�. Select 1. This puts the calculator in Statistics Mode.

- Enter the first number, 1.
- Hit the M+. (n= 1 will appear in the window)
- Enter the second number, 1.
- Hit the M+ key.� (n=2 will appear in the window)
- � . . .

. . - Enter the last number, 7.
- Hit the M+ key.� (n=7 will appear in the window)

- Hit shift, 2. (This invokes the S-Var option.)
- Hit 1 for the sample mean. Hit Enter.
- Hit 3 for the sample standard deviation that

we will use in class. Hit Enter.

deviation by hand, I am looking for s_{x}_{� }not the other listed values.

**TI-36X **

- Hit the 2
