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

If you want to do that do not buy an 83 or 83+. all the 84's and all the 89's come with usb chords so you can hook them up to the computer, now how you do that i don't know cause i use an 83. You would have to do more research. I hope this can help. GOOD LUCK

The TI-30Xa does not have a statistics mode. That statistics operations are available at all times, just like addition and subtraction. Just enter the data with Sigma-plus and then calculate the desired statistics---mean, standard deviation, and so forth.

Full details are in the "One-Variable Statistics" section of the guidebook (page 9 in my copy). If you need the guidebook, you can download one from

you mean edit - just do 2nd , then window, walla - use your arrows to navigate and reset numbers, sometimes you need the table setup for the statistic and probability calculations - get the ti for dummies, and there is a statistics ti 84 book also that helps a lot.

get the TI 84 for dummies book, and check the statistic functions - they are fantastic - got me an A in statistics - once you start using them, you must practice- a function for everything!!

The 30XA doesn't have a statistical mode; all of the statistical functions are available at all times.

2nd [CSR] clears the statistical registers, Sigma+ adds a data point, Sigma- deletes a data point, 2nd [x-bar] gives the mean, 2nd [sigma-x-n] and 2nd [sigma-x-n-minus-one] give the population and sample standard deviation.

For full details, refer to the statistics section in the manual. If you don't have a manual, you can download a guidebook from

The truth of the matter is that there is no statistical mode per se. You just start entering data in a specific sequence.

If there is data in the statistics register (remnant of and old calculation) you must start by clearing old values :[2nd][CSR].

Here is a screen capture with an example that uses frequencies.

The actual error message you get is designed to help you diagnose potential error conditions. It is very helpful to know what message was generated. Anyway, I will do my best to guess.

Deactivate the statistical plots.

Press [2nd][Y=] to access (STAT PLOTs)

Select [4:PlotsOff] then [ENTER]

That should solve your problem. Post a comment to this thread if you still have trouble graphing.

Click
on the Mode button twice until you see
“SD”. Select 1. This puts the calculator in Statistics Mode.
Enter the first number, 1.

Hit the M+. (n= 1 will appear in the window)

Enter the second number, 1.

Hit the M+ key. (n=2 will appear in the window)

. . . . .

Enter the last number, 7.

Hit the M+ key. (n=7 will appear in the window)

Hit shift, 2. (This invokes the S-Var option.)

Hit 1 for the sample mean. Hit Enter.

Hit 3 for the sample standard deviation that we will use in class. Hit Enter. here you can also ffind the sum of all numbers

"x bar" returns the mean of a series of numbers entered in "statistical mode".

e.g.enter 3, then press the "sigma plus" key (just above the "STO" key. Display will show "n = 1" and "STAT" will display to remind you that you are in statistical mode.

Enter 3 the "sigma plus" and you will see "n = 2" to tell you that you have entered two numbers. Keep doing this for a few more, then press "2nd x bar" and you will see the mean of all the numbers you entered, which is 3 if you entered all 3's.

To exit "STAT" mode, you have to press "2nd" then "CSR" (just above the 7 key), since the regular "clear" key only clears the pending entry.

Lots of simple statistical stuff you can do on the TI-30XA, read the guide book, available online at TI if you don't have one

You can't, the TI-30XA is a one variable statistical calculator, so you can't do two variable statistics with it.

You need to step up to the TI-35X or the TI-30X IIS

I already answered a Q like this - you can't do 2 variable statistics on the TI-30XA, it only does one variable statistic.

To do 2 variable stat like linear regression, you need the TI-36X or TI-30X IIS, or comparable HP, casio etc

Thanks Pboy

I'll continue the research, but form the sound of what you are saying if I can hook the calculator to a PC I may be able to cut and paste into the report.
