Question about Casio ClassPad 300 Calculator

Turn ClassPad ON.

Press [MENU]

Find the STATISTICS application and tap its icon.

Enter your data in one column (L1) and frequency values in List 2.

If all frequencies are equal to 1, no need to enter them in L2.

After you finish entering the data, Tap the CALC menu at the top of screen.

Select One-Variable (or two variables if you want regressions) and tap the OK button. You are given the opportunity to select the data list and the frequency list, if any.

Validate your choices. and tap OK.

Statistical values are displayed. The display runs more than one screen. Use the downHow do i perform standard - 63683fa.jpgroll.

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.

goodluck!

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.**

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

Hello,

I am afraid I do not understand. The frequency of a PARTICULAR score is the number of times that particular value occurs in the data. It is not the number of data.

Ex: the data are:

4, 6, 5, 4, 4, 8, 9, 3, 3, 6, 7

Frequency of (3) =2

Frequency of (4)= 3

Frequency of (5) =1

Frequency of (6)= 2

Frequency of (7)=1

Frequency of (8)=1

Frequency of (9)=1

Number of data =11 (n=11)

You compute the mean M

M= (2x3 + 3x4 +1x5 +2x6+1x7+1x8+1x9) /11 =5.363636..

As you can see, if a term is not repeated it is multiplied by 1 (its frequency is one). Value 3 occurs twice (hence 2x3); value 4 occurs 3 times (3x4), etc.

To calculate by hand the sum of squares

**3:** (3-5.3636)^2 + (3-5.3636)^2 .................... = **2x(3-5.3636)^2**

**4:** (4-5.3636)^2 + (4-5.3636)^2 +(4-5.3636)^2 = **3x(4-5.3636)^2**

**5:** (5-5.3636)^2 ...................................... .= **1x(5-5.3636)^2**

**6:** (6-5.3636)^2 +(6-5.3636)^2......................= **2x(6-5.3636)^2**

**7**: (7-5.3636)^2.......................................... .=**1x(7-5.3636)^2**

**8**: (8-5.3636)^2......................................... ..=**1x(8-5.3636)^2**

9: (9-5.3636)^2......................................... ..=**1x(9-5.3636)^2**

If I have not made a mistake the sum of squares is 40.5454

**Standard Deviation**

The standard formula above gives s= square root (40.5454/10) =2.01

** Population Standard Deviation**

The population Standard deviation above is S= square root (40.5454/11) =1.9198

So if you perform the calculation with the calculator the only times you need to enter the frequency is for repeated terms. When you have to enter 6 above, its frequency is 2 you proceed as follows

**6 [2nd][FRQ] 2 [Sigma+]**

Once you entered the raw scores, the calculator does the rest.

Hope it helps.

Hello,

Of course there are formulas for those calculations.**You find them in books on statistics.** Do not worry, the calculator has been programmed to use them. All you have to do is learn how to get the calculator to give you the results.

If you still want to see the formulas with your very eyes, I suggest you go to the local library, ask a math teacher, an accountant, or launch a Google search for them.

Hope it helps.

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+

I want to calculate a standard deviation on BA II plus

Apr 23, 2008 | Texas Instruments BA-II Plus Calculator

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).
