Data for statistical analyses is stored in lists, which you can
create and edit using the stat list editor. The TI-82 STATS has
six list variables in memory,
L1 through L6, to which you can
store data for statistical calculations. Also, you can store data to
list names that you create (Chapter 11).
To set up a statistical analysis, follow these steps. Read the
chapter for details.
1. Enter the statistical data into one or more lists.
2. Plot the data.
3. Calculate the statistical variables or fit a model to the data.
4. Graph the regression equation for the plotted data.
5. Graph the residuals list for the given regression model.
The stat list editor is a table where you can store, edit, and view
up to 20 lists that are in memory. Also, you can create list
names from the stat list editor.
To display the stat list editor, press …, and then select
1:Edit
from the STAT EDIT menu.
The top line displays list names. L1 through L6 are stored in
columns
1 through 6 after a memory reset. The number of the
current column is displayed in the top-right corner.
The bottom line is the entry line. All data entry occurs on this
line. The characteristics of this line change according to the
current context (page 12.17).
The center area displays up to seven elements of up to three
lists; it abbreviates values when necessary. The entry line
displays the full value of the current element.
