SOURCE: steps from manual on how to do stemp plot box

To make a plot, first you will need to define a list. To do this, press "{", then enter the values of your list, separating each value with a comma, and ending the list with "}" then store (STO>) the list into a list variable ("2nd" + "1", "2", etc.). For a box plot, you will need only one list, and for a scatter plot, you will need two. One for the independent variable, and one for the response variable; that is, one for the X and Y axis, respectively. To make your plot, open the plot menu ("2nd" + "Y=") and select a plot. From there, you may select the type of plot and which lists to use as values.

To find the residuals for the line of best fit, from the home screen, press "STAT", then move one right to "CALC", then select option 4, "LinReg(ax+b)". Once this command is on your home screen, follow it with your X and Y axis lists, separated by a comma, eg: "LinReg(ax+b) L1, L2". Press enter. In a moment, you will be provided with 'a' and 'b' values. Plug those residuals into your "Y=" menu in the form "ax+b", replacing 'a' and 'b' with the residuals, and the line of best fit will be drawn across your graph.

SOURCE: I entered and calculated data

If you have a frequency list it must be entered in a statistical list, L2, L3, ...or L6.
If the frequency of all elements is 1 you do not need to enter the frequency in a list. When you go to draw the box plot, the frequency will be set to 1.

Hey. I had the exact same problem as you and all I could do was reset the settings to the default settings on the calculator. All you have to do is turn the calculator on, his 2nd (it should say mem right above it). Then click reset then RAM.

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?


Hi,
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.

Cannot graph invalid dim error


This error show up when you are graphing out of the plot menu. If you are not graphing data points from list menu, you need to turn the plots off. In the y= screen, you will see the words plot 1, plot 2, etc across the top of the screen. If one of the plots is highlighted (black box over the words), you need to turn it off. This can be done by arrowing up and highlighting the box and pressing enter. When you arrow back down, the plot should be off and you will be able to enter an equation in the y= lines and graph.

If you are graphing from the plot menu, this error lets you know that one of the lists you are graphing is longer than the other.

Another way to fix the problem is to reset the calculator by pressing 2nd button then plus sign then 7 then 1 then 2. This will reset the calculator however if you are graphing from lists, your data will be erased. Hope this helps.

Having trouble with my TI-83 plus


Hello,
Some old junk is in memory. Reset the memory to defaults and everything will be fine. It is a good practice to clear memory before a new calculation.
To reset memory
Press [2nd][MEM][7:Reset][1:All ram][2:Reset] [EMTER] . Clear screen and enter the functions you want to graph.
Hope it helps.

List dimensions


This is a pretty vague problem but not much of a problem. Your actualy plotting device of your stat plot is under your "y=". But before you do that you need to hit the stat button right next to the blue apps button. Then hit edit. These are your stat data1.gif. If you are trying to add data in you should notice what list they are under. (top of the screen L1, L2, ect.) You should also make sure that the number of data adds up for your two list. Now that you have done that you can go to "2nd" then hit "y=". If you don't want to graph your stat plots just make sure they all sat plot... off by hitting enter on the one that says that it is on. Now if you want one on hit enter and make sure your lists from your data match up with your stat plot. You can hit enter and see what one you need. they are above the 1, 2, 3, etc key. Hope this works. If all else fails you can clear your calculator by pressing "2nd", "+", "7", "1", "2". This will turn off all your stat plots if you have trouble understandsing this. But most importnat make sure your L1 and L2 match up on your stat plot with your list under your stat edit. If you don't understand this just i can help you out some more
