Basics#

Setup#

Statistics Diagnostics Mode#

Some output that will be useful in this class is suppressed by default. To ensure all relevant information is output, go to the MODE menu,

  • \text{BUTTON} : \text{MODE}

Scroll down to Stat Diagnostics. If necessary, switch Stat Diagnostics mode to on.

Initialize Lists#

Sometimes lists are deleted from the calculator’s memory (intentionally or otherwise) and will need restored. To do this, execute the following,

  • \text{BUTTON} : \text{STAT}

  • 5 : \text{SETUPEDITOR}

Lists#

A list variable is the TI-83/84 family’s way of representing sets.

Warning

Technically, mathematical sets do not allow for duplicated values. A list on your TI is an ordered set, meaning duplicate values are distinguished by the order in which they occur, i.e. the following list on a TI

L_1 = \{ 10, 10 \}

has two elements, because each 10 also has an order associated with it. In pure set theory, both 10’s would be considered the same element.

Creating and Editing#

Spreadsheet#

The easiest way to edit lists through the Spreadsheet Editor. The Spreadsheet Editor can be accessed with the following command sequence,

TODO: insert some pictures

The first row of the list spreadsheet is a row of headers that identify which list corresponds to which column. Data can be entered directly into the lists by using the arrow keys and the ENTER button.

Store#

Alternatively, lists can be stored into list variables using the \implies button.

Entering this sequence of buttons will be shown on the main screen of the calculator as follows,

\{ 1, 2, 3 \} \implies L_1
