[. . . ] Press } to move the cursor to the top line. 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 , and then edit the formula. 4. . Note: If you do not use quotation marks, the TI-84 Plus 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 symbol (Chapter 11). Chapter 12: Statistics 188 5. The TI-84 Plus 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. lock symbol Using the Stat List Editor When Formula-Generated Lists Are Displayed When you edit an element of a list referenced in an attached formula, the TI-84 Plus updates the corresponding element in the list to which the formula is attached (Chapter 11). When a list with a formula attached is displayed in the stat list editor and you edit or enter elements of another displayed list, then the TI-84 Plus takes slightly longer to accept each edit or entry than when no lists with formulas attached are in view. Note: To speed editing time, scroll horizontally until no lists with formulas are displayed, or rearrange the stat list editor so that no lists with formulas are displayed. Handling Errors Resulting from Attached Formulas On the home screen, you can attach to a list a formula that references another list with dimension 0 (Chapter 11). However, you cannot display the formula-generated list in the stat list editor or on the home screen until you enter at least one element to the list that the formula references. All elements of a list referenced by an attached formula must be valid for the attached formula. For example, if Real number mode is set and the attached formula is log(L1), then each element of L1 must be greater than 0, since the logarithm of a negative number returns a complex result. When you use the shortcut menus, all values must be valid for use in the templates. Press to switch to edit-elements context. All elements of the current list are displayed in braces ( { } ) in the entry line. Press ~ and | to view more list elements. Press again to switch to view-elements context. Press ~, |, ?, and } to view other list elements. The current element?s full value is displayed in the entry line. 4. Press again to switch back to edit-elements context. You may edit the current element in the entry line. 5. Press } until the cursor is on a list name, then press y 6 to switch to enter-name context. 6. to switch back to view-elements context. Chapter 12: Statistics 191 Stat List Editor Contexts View-Elements Context In view-elements context, the entry line displays the list name, the current element?s place in that list, and the full value of the current element, up to 12 characters at a time. An ellipsis (. . . ) indicates that the element continues beyond 12 characters. To page down the list six elements, press ? [. . . ] The previous screen is displayed with the cursor at or near the error location. Correct the expression. Refer to the Error Conditions table for details about specific errors, if necessary. If the busy indicator (dotted line) is displayed, a graph or program has been paused; the TI-84 Plus is waiting for input. If a checkerboard cursor ( # ) is displayed, then either you have entered the maximum number of characters in a prompt, or memory is full. [. . . ]
