Setting Up Statistical Analyses
Using Lists to Store Data
Data for statistical analyses is stored in lists, which you can create and
edit using the stat list editor. The TI-83 Plus 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).
