TI-34 mean, median, mode


Mean= average =(sum of data values)/(number of data values)
Mode is the most frequent data value.
Median: Sort the data in ascending order. The element in the middle is the median.
If the number of data is odd, there will be one MIDDLE element. It is the median.
If the number of data is even, there will be two elements in the middle. Add the values of these middle elements and divide by 2. The result will be the median. It is not part of the data.

How do i find grouped data in L1 and L2 on ti 82


I am not sure I understand but if it the same problem as in your other posted question, here is what I wrote.

Are the data in L1 and l2 in any way related? If they are (being x-values and y-values of some data set) then you need to do regression analysis (2-var stats)
If they are not related (connected) you can calculate the mean of each group separately.
Do 1-var stat by specifying the L1 list first (may be the default), get your average of the values in L1. Then you can do 1-var stat on the data in L2 by specifying the list L2 on the command line.
1-var L2 ENTER
Note: What I am describing here is valid for the TI 83 Plus/TI84 Plus, but I suspect the steps are similar to the TI 82.

There's a blank bar that runs horizontal in the middle of my TI-84 plus that's about 16 pixels wide(high?). It's the same color as when the device is turned off. I've tried a memory reset and no results....


SPLIT SCREEN.

It sounds as if you might have split screen mode on. I've got a TI-83 as well as a TI-89 Titanium, both offer a split screen mode. The latter allows for choosing which applications are displayed on each half screen. I am presuming that you may have accidentally put your TI-84 in this mode.

So, if it is a split screen deal then all you have to do is go to the mode screen, find the option for switching from split screen to full screen, and switch it back to full.

I hope that helps. Give us your results!

Adios

Whenever i try to link my calculator with other ones it always says error in xmit. no matter what i do


Hello,
Read the following answer from the TI Knowledge Base.
Hope it helps.

How can I troubleshoot an Error in Xmit error message when transferring data between two graphing calculators?

The Error in Xmit error message is returned when a connection cannot be established between two calculators when attempting to transfer data. There are several factors that can contribute to this error message.
• The calculators being connected are not compatible for data transfer.
• The data cable is not firmly connected to both units.
• The receiving calculator is not in receive mode.
• The I/O port on one of the graphing calculators is damaged.
The procedure for connecting two graphing calculators is as follows:

• Connect the data cable to the I/O port of each unit. The cable will fit tightly in the I/O port and snap into place. If silver from the cable is visible, the cable is not properly connected.
• Access the Link menu on each unit
• Place the receiving graphing calculator on "Receive"
• Place the sending unit on "Transmit" or "Send" from the Link menu.

Once the data has been selected, the transfer will commence accordingly.

The data transfer protocols for graphing calculator is as follows:

• TI-73 - Link allows data sharing with another TI-73, TI-82, TI-83, and TI-83 Plus.
• TI-82 - Link allows data sharing with another TI-82.
• TI-83 - Link allows data sharing with the TI-82, TI-83 family calculator, and TI-84 Plus family calculator.
• TI-83 Plus/TI-84 Plus family- Link allows data sharing with another TI-82, TI-83 family calculator, and TI-84 Plus family calculator.
• TI-85 - Link allows data sharing with another TI-85(To a TI-86. Not From a TI-86).
• TI-86 - Link allows data sharing with another TI-86 and from a TI-85 to a TI-86.
• TI-89 family- Link allows data sharing with another TI-89 family calculator and from a TI-92 family calculator.
• TI-92 family- Link allows data sharing with another TI-92 family calculator and from a TI-89 family calculator.
• Voyage™ 200 - Link allows data sharing with another Voyage 200 and TI-92 family calculator.



If the cable does not fit properly into the I/O port, or if the I/O port appears to be damaged (broken or separated plastic, obstruction inside the port), call 1-800-TI-CARES (1-800-842-2737) M-TH 8:00 AM - 7:00 PM FRI 10:00 AM - 7:00 PM Central Standard Time to speak to a representative or sending an email to ti-cares@ti.com.

My TI83 screen is not functioning correctly. some lines do not read numbers when I press them in


Do you mean that some of the pixel columns don't work? As in "empty pixels"? If so, I don't think there is a way to solve this problem, and you can either deal with it or buy a new calculator

TI-82 Screen Not Working or Black


Try a hard reset. Take out all the batteries, and while putting them back in, hold down the "DEL" key. Then, turn it back on and you can adjust the contrast by pressing the "2nd" key and the down arrow at the same time. I just got this info. online and it finally worked for me...good luck!
