Clear the statistics registers with 2nd [CSR]. Add the data points with Sigma+. Errors can be corrected with 2nd [Sigma-]. Calculate the mean with 2nd [xbar].

See the example on page 11 of this guidebook.

You need to select the number of decimal places you would like, or if you would like the calculator to behave as normal. Press SET UP and select FSE (press 1) . You now have 5 options.

0: FIX means you can choose a fixed number of decimal places for every calculation.

1: SCI means scientific notation and choose the number of significant values you would like to deal with.

2: ENG means engineering and the power goes up in multiples of 3.

3: NORM1 and 4: NORM2 are the usual or normal settings on the calculator. Most school calculations will use NORM1 mode.

Here is one technique I used on the TI84Plus.

Create two lists list1(50) and list2(50) of equal dimension (same length)

You will have to find how to do it on ClassPad.

Fill list2 with zeros

Fill list1 with your data.

Sort the list in ascending order (if it is not sorted)

Do standard deviation calculation on list1 (or calculate the average)

The mean of the data is in a special variable (xbar)

From the command line using the list syntax calculate abs(list1-xbar) and store results in list2, overwiting the zeros.

Perform standard deviation on the new list2. You will get the mean deviation from the mean in the variable xbar.

**A simple request from you**. Can you please not use MINUS as a verb? By doing so you are propagating incorrect usage. There is a short and correct way to express the operation:** to add.**

If you mean "BEG" then press g [END] (the blue "g" key followed by the "8" key) to switch to the end payment mode.

If you do mean "deg" but on a different calculator, then please reply to this post and specify the calculator.

Full instructions are in the "Statistical Calculation" section beginning on page E-44 of the manual. If you need a manual, you may download a copy here.

In short, you go into the STAT mode, bring up the STAT Editor screen, enter the 50 data points, then calculate the mean and standard deviation.

for the mean, just add them together and divide answer by the amount of figures you put in.
as for the others, i'm not sure a standard scientific calculator will do that

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).
