Problem Solving > List on the TI89
Entering data into a list is one of the most important functions you can learn to do on the TI-89. Lists of data are a must for calculus and may other subjects that use list data, like statistics. You can use a list of data to model data, produce scatter plots, and problem solve functions.
You’ll need to have the stats/list editor installed. You can download it from the official TI website here.
