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.

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)
Goodluck!

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.

When I enter some series of data and check the descriptive statistics, every time I come to the standard deviation the calculator shows me Error 1 message.

Is there a PDF with the Statistical procedures for this product? I bought my Casio FX-115 used (second hand). No instructions. I need help using the Statistical functions for my Stats classes:
Correlation Coefficient
Standard Deviation/Variance
Chi-Square
x-x(bar) summations
HELP!

### 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 I put my calculator in statistics mode?

The TI-30XA does not have to be switched to a statistics mode, the operations are available all the time. The choice of operations are somewhat limited; the calculator offers statistics functions for one dimensional data sets only (no linear interpolation of (x,y) value pairs, for example):
• [2nd] [CSR] - erase statistics data
• [] - add a number to the sample set
• [2nd] [] - remove a number from the sample set
• [2nd] [FRQ] - multiple entry of the same sample value
• [2nd] [n] - sample set size
• [2nd] [] - sum of all sample elements
• [2nd] [] - sum of the squares of all sample elements
• [2nd] [] - average of the sample set
• [2nd] [] - standard deviation (sample set is a complete set)
• [2nd] [] - standard deviation (sample set is a subset of a larger set)
The calculator displays "STAT" if the current sample set is non-empty.

Example: calculate the average and standard deviation of the set { 3, 4, 5, 5, 5, 5, 6 }.
1. [2nd] [CSR] - erase stat memory
2. 3 [] 4 [] 5 [2nd] [FRQ] 4 [] 6 [] - enter the data, note the use of [2nd] [FRQ] to enter the four occurrences of "5". Entering 5 [] four times would have done the same.
3. [2nd] [] - display the average of the set, (4.714...)
4. [2nd] [] - display the standard deviation of the set (0.8806...)

### How do i solve standard deviation with this calculator

The stdDev( function in the LIST MATH menu will calculate the standard deviation of a list. You can provide a second list if the data is grouped.

For detailed information refer to the "Lists", "Statistics", and "Infererential Statistics and Distribution" chapters in the guidebook. If you've misplaced your guidebook you can download a copy from

### 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].

### I have a Casio fx 300 and i am taking a stats course.

Hello,
Even a smile requires the contraction of about a dozen facial muscles. So here is how you do it (not the smile, the standard deviation).

Hope it helps.

### Standard Deviation

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).
