### What is a cas calculator

Some high-end calculators have a Computer Algebra System built-in. These systems can do symbolic algebra, that is, with symbols instead of numbers, for example factoring a^2-b^2 to produce (a+b)(a-b).

The TI-30x isn't one of them.

### How do I compute population standard deviation on the TI 84 plus?

Put the data into a list using whatever scheme you prefer. Press STAT right-arrow to bring up the STAT CALC menu. Select "1-Var Stats" and specify the list containing the data. You'll get a screen showing the various statistical values. The population standard deviation is designated by a lowercase sigma.

### I am trying to find the variance can this be found with the TI-30X II S I have the Texas Instruments TI-30 X II S on solar batteries, it has 2nd function but i am not sure how to find the summation for...

So you press 2nd Function , select 1-Var or 2-Var (for paired datat) then enter your data pressing down arrow after each and Enter to finish then press STAT / VAR to see the various variables

Please give me a thumbs up if this helped

### Find the standard deviation of the following data set 5,5,5,5

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.

### I'm using the TI-30X IIS calculalator and cannot calculate the standard deviation. Please help! Thank you!

Press 2nd [STAT] then select CLRDATA to clear statistics data. Select 1-VAR or 2-VAR for one-variable or two-variable statistics. Press DATA and enter your data (x for 1-VAR or x and y for 2-VAR). Press 2nd [EXIT-STAT] and select N. Press STAT-VAR to see a menu of statistics variables and their values. Sx (and Sy) will give you the standard deviation, sigma-x (and sigma-y) will give you the population standard deviation.

### 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

### Standard Deviation

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.

### 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).
