Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator

# Standard deviation and other answers

I can make a list(l1) and run the calc to get most the answers I need. But how do you do the same thing with a freqlist in addition to the first list?

Sample: list 1=25,40,60,75,93 freqlist=30,50,20,40,30

Thanks
John

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).
Good luck!

### 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.

### How do I get the variance on the calc.

The following is an example for the dataset {5,7,18}. This will generalize to any dataset that you would like to use.
Press "5", "SIGMA+", "7", "SIGMA+", "1", "8", "SIGMA+"

2. Calculate the standard deviation
Press "2nd", "sigma_(x n-1)"

3. Square the standard deviation to get the varience:
Press "x^2"

If you followed the correct steps you should see "49" as your answer.

### How do i perform standard deviation,correlation coefficient and least square regression line on the casio class pad? Thank you so very very much - it is for an exam tomorrow.

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 downArrow to scroll.

### How to i do std deviation and sample mean

Example: Enter the following x variables, and determine the sample and population standard deviations.
x = {1,2,3}
• Press [DATA] and begin to enter the data as indicated into the L1, L2 or L3 lists. To input a data point, type the value and press [ENTER]. Press the down arrow key to move on to the next data point.
• Press [2nd], [STAT], and then choose 1-VAR.
• For the "DATA" option, choose the listname the data is stored in (L1, L2 or L3). For the "FRQ" option, choose "ONE" since this data does not include a frequency list.
• Arrow down to "CALC" and press [ENTER].

3:Sx (Sample Standard Deviation) = 1
4:sx (Population Standard Deviation) = 0.816497
• Press [2nd] [MODE] to exit STAT mode.

### When I type a list of numbers into L1 and then hit Stat, calc, 1-var stats L1. i get invalid dim

1. Press [STAT][5:SetUpEditor][ENTER].
2. Press [STAT][1:Edit..]
3. Enter your data in L1.
4. Press [STAT][CALC][1:1-Var Stats].
5. Command echoes on main screen.
6. If ONLY one list contains data, it must be L1.
7. When you do not specify the list in the command line it will take L1 by default.
8. If L1 is empty and the data is in L2, or another but L1, the name of list must be specified.

### Standard deviation

pulse F1(CALC), F1(1VAR) and it goes to 1-Variable Screen and shows the following:
x-(mean): 49.3333333
Sumx:296
Sumx^2:15066
xon:8.78761755
xon-1:9.62635271
n:6

I guess that you wanted the x- and xon

Also are available in RUN mode through VARS, F3(STAT), F1(X), F2(x-) and F5(xon)

### 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).

### Standard deviation

1. Put the data into a list.
2. OneVar list will produce a screenful (and more) of one-variable statistics.

OneVar is available through the STAT CALC menu. "list" in step 2 is the name of the list created in step 1.

### Standard deviation

Here goes if you still need this...

STAT, EDIT, put information into L1 if only one variable stats, but put info into L1 and L2 if it is frequency table stats.

Then choose Stat, over to CALC, 1, enter...if 1 variable stats then press enter again. If frequency table stats, then choose STAT, over to CALC, 1, 2nd, 1 [L!], 2nd, 2 [L2], enter.
