Entering Statistical Data
Data for statistical analysis is stored in lists, which you can create and edit in the list editor
(Chapter 11), on the home screen (Chapter 11), or in a program (Chapter 16). The TI
-86 has
three built-in list names for statistics, xStat (x-variable list), yStat (y-variable list), and fStat
(frequency list). TI -86 statistical functions use these lists as defaults.
