Attaching Formulas to List Names
Attaching a Formula to a List Name in Stat List Editor
You can attach a formula to a list name in the stat list editor, and then display and edit the calculated
list elements. When executed, the attached formula must resolve to a list. Chapter 11 describes in detail
the concept of attaching formulas to list names.
To attach a formula to a list name that is stored in the stat list editor, follow these steps.
1. Press … Í to display the stat list editor.
2. Press } to move the cursor to the top line.
3. Press | or ~, if necessary, to move the cursor onto the list name to which you want to attach the
formula.
Note: If a formula in quotation marks is displayed on the entry line, then a formula is already
attached to the list name. To edit the formula, press Í, and then edit the formula.
4. Press ƒ ããä, enter the formula, and press ƒ ããä.
Note: If you do not use quotation marks, the TI-84 Plus C calculates and displays the same initial list
of answers, but does not attach the formula for future calculations.
Note: Any user-created list name referenced in a formula must be preceded by an Ù symbol
(Chapter 11).
5. Press Í. The TI-84 Plus C calculates each list element and stores it to the list name to which the
formula is attached. A lock symbol is displayed in the stat list editor, next to the list name to which
the formula is attached.
