So when i first installed the stats list editor program from the TI website (why this calc didnt come with the program is beyond me), the histograms I created displayed perfectly with the "ZoomData" command. Now for some reason, they display all out of whack with some of the data across the y axis, i can see some blank space below the x axis, and I can't figure out why. I have turned off all plots and functions, my y= is completely clear, and i have cleared all RAM as well.
Anyone know whats going on? I have a test coming up, and i just want to display my histograms cleanly and easily!

To get the correlation coefficient, open the CATALOG by pressing [2nd] 0 (CATALOG) Press the [x-1] key for the letter D Scroll down from the cursor position to reach DiagnosticsON. Highlight the command and press EXE.
Use the statistic utility Press the STAT key. Press 5 to execute the SetUpEditor command Press the STAT key again then 1:Edit Enter an x-values in list L1, and the corresponding y-values in list L2. This way if your data set is not sorted in x, you can use the SortA( command. After you enter the x- and y-values, exit the Editor Press the STAT key then scroll once to CALC Select 2:2-var Stats. The command will echo on the main screen. Press EXE to execute it. If there are no errors you statistics will be diplayed. Among them you will see R^2.
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.
Most of the time when you get the "invalid dimenstion" error, either list 1 or list 2 is longer than the other. Check your data and make sure you there are not more numbers in one list than in the other.
Another posssibility is that when you tried to clear list one, you may have deleted list one. If this is the case, you can get the column labeled list one back by pressing stat, then select set up editor form that menu which will take you back to the home screen. Press enter and the word done will appear. Now when you go back to stat edit, list one will be there.
