Fx- 9750gii ... I deleted the table on my table

If the table contains experimental (statistical) data that you gathered and put in a table on the calculator, then I am sorry to say that if table is deleted there is no way to get the data back. You will have to renter it.
However if it is a table connected to a function you graphed then the table can be regenerated: Type in the function anew, press the table function key, then graph it.

My TI-84 will graph but it will not show me the table of values. It just shows up blank.

Enter the function using the Y= editor. Pressing [ 2nd ][Graph] (table) will display the table. You can then press [GRAPH] to see the grapg. If you want both graph and table side by side use the split screen feature.
To do so press [Mode]. Scroll down to the last line Full Horiz G-T. Highlight the option G-T. Press the Graph key.

If you want the table to be generated, you must use the table feature. You can generate a table also after you draw (graph) a function.
Enter a function in the Y= editor, then press GRAPH or SHIFT GRAPH (TABLE). If you press GRAPH, you will see a graph. If you want the table and are not interested in the graph, press SHIFT TABLE.

When you graph a function,where can I find the table??

I find it easier to generate the table then look at the graph. Here how you go about it, illustrated with screen capture taken from the newer version of the calculator. k24674_7.jpg
Press the MENU button.
Use arrows to highlight the TABLE application (1st screen).
Enter a function expression in Y1=
And press the function key F6 under the TABL menu tab. (2nd screen)
A table is generated (3rd screen)
Press F5 (G-CON) for a connected graph, or F6 (G-PLT) for a dotted graph.
The graph is shown (4th screen).
Use the Zoom function (ZoomAuto) or any other Zoom or change the window dimensions to suit your needs.

I'm using the application that simulates tossing a coin a certain amount of time and graphs the frequency that heads and tails come up. I need to make a histogram from it; how can I export/transfer the...

If you are using the ProbSim application to toss a coin, the histogram is drawn after each set of tosses.
  1. Toss a certain number of times using the +10 or +50 tabs.
  2. To export the data (a big word for just two numbers) stop tossing the coins by pressing the key under the tab [ESC] (the Y= key).
  3. The bottom of the screen will display 5 tabs :[ESC], [TOSS], SET],[DATA], and [TABL].
  4. Press [F5] to activate the [TABL] menu.
  5. Your screen will display a table with 3 columns: TOSS for the toss number, 1 for the result of the toss (Head or Tail), and the last column CumH the cumulative number of Head results.
  6. At the bottom right of the screen you have a menu [GRAPH] above the GRAPH key.
  7. Press the Graph key to execute the Menu graph.
  8. The histogram is drawn.

I accidentally deleted they y column from my

If that Y-Column was created by a function (Y1=...) recreate the table by pressing [2nd][GRAPH] (TABLE).
If the column is a list of statistical data that you entered, there is no way to restore it. Just reenter the data anew.

Hi, I can edit my table information in my calculator but am not able to graph from it and when i go to table it shows nothing.. what do i do?

From what I understand you want to draw statistical graphs (scatter plot, box plot, etc.) If you do not see anything it may be due to the fact that the statistical plots are turned off.

Type in the data in lists L1 and L2, etc. Press [2nd][QUIT]

Press [2nd][Y=] (STAT PLOT] . Select [4:PlotsOff] [ENTER] .
Screen displays Done

Press [2nd][Y=] (STAT PLOT] . Select [1:Plot1 Off].
  1. The configuration screen for Plot1 opens with the cursor blinking ON.
  2. Press [ENTER] to turn Plot1 ON.
  3. Use Down Arrow to move cursor to second line Type:
  4. Select the type of statistical plot. Use the right arrow to move highlight on one of the 6 types.
  5. Select the type:scatter, Xline, histogram, box plot, and press [ENTER] to validate the choisce.
  6. Use down arrow to select the Xlist: use [2nd][1] to choose L1, etc. and press [ENTER]
  7. Select the Y-List (L2) and validate by pressing [ENTER]
  8. Select the data-point mark.
  9. Press [GRAPH].
If you do not see the graph or if it is not well centred, press [ZOOM][9:ZoomStat] to restrict the screen to the data entered.

Hope it helps.
Thank you for rating the solution.

Help me please

Sorry if you already know that, but I want to make sure we understand one another.

Say you want to graph the function Y1=2X+3.
You press [MODE] to make sure that the FUNC on 4th line is highlighted permanently. If it is you press [Y=]

On the first line where it says Y1= you enter 2*[X,T,Theta,n] +3.
The X is accessed with the key to the right of the [ALPHA] key.
As you key in your function, notice that the equal sign after Y1 is highlighted and remains so. When you finish entering the function press [ENTER] so that the cursor moves to the line Y2=. Make sure that the = sign after the Y1 in previous equation remains highlighted.

You can now draw the graph by pressing [GRAPH] or generate the table Y1=f(X) by pressing [2nd][TABLE]. Under no conditions should you enter YOUR own values. If the table does not appear there may be a problem, and you will not solve it by entering values.

Now let us try to get you calculator to work as it should.

Press [2nd][STATPLOT][4:PlotsOff] , the command PlotsOff echoes on main screen. Press [ENTER] to turn statistical plots OFF. Screen displays Done.
Press [2nd][CATALOG] [ENTER]. The list of all avilable command appears. Scroll down till you reach ClrAllLists. Move arrow to the correspondig line and press [ENTER] , command echoes on main screen as ClrAllLists. Press [ENTER] to erase all old statistical lists that may be stored in the calculator memory.

Now you are ready to graph or create the table of values. Press [2nd][Table] and the table should be displayed. All you can do with the values in the table is to look at them, examine them. You cannot modifie nor erase them.

If, for reasons of your own, you think you ought to be allowed to enter YOUR values, in the table, then this is not graphing functions. The name for that is DOING STATISTICS. And the procedure is tottaly different: You enter YOUR values in lists and use the calculator to draw the data points, and to find the best fit (the curve that models the pattern of data distribution best). When you decide which fit is the best, you can use the calculator to extract the equation for the curve and, if you want it, to draw the curve on the same graph where you raw data is represented.
Hope these clarifications helps.

No Y table when i want to enter the numbers for a graph. I press 2nd graph and there is no Y table. I read that to fix this you would have to press "Y=" and enter a function. But when I do, the Y table is...

It is noranl that you cannot enter data in the table becuase it was generated from the function you entered. If you specify the function you cannot specify the data in the table. But if you want to enter you own values, that is doing statistics, not graphing functions.
To do stats
Press STAT button, then select 5: SetUPEditor ENTER ENTER. You do that to reset calculator to do stats.
After that press STAT again, and select 1:Edit. The lists open to you and you can enter your data in the lists

But not knowing what you really want to do, I cannot advise you better.
Hope it helps.
