Page Using Lists to Store Data Using Lists to Store Data Data for statistical analyses is stored in lists, which you can create and edit using the stat list editor.
Page can store data for statistical calculations. Also, you can store data to list names that you create Chapter Page The top line displays list names.
The number of the current column is displayed in the top-right corner. The bottom line is the entry line. All data entry occurs on this line. The characteristics of this line change according to the current context. The center area displays up to seven elements of up to three lists; Enter a valid list name in any of four ways. The rectangular cursor is displayed. If the list name you entered in step 2 already was stored in another stat list Note: editor column, then the list and its elements, if any, move to the current column from the previous column.
Page You can enter expressions and variables for elements. Note: 4. If you entered an expression, it is evaluated. If you entered only a variable, the stored value is displayed as a list element.
When you edit a list element in the stat list editor, the list is updated in memory immediately. Page Note: symbol Chapter The TI 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. Page As described above, one way to detach a formula from a list name is to edit an element of the list to which the formula is attached.
The TI Plus protects against inadvertently detaching the formula from the list name by editing an element of the formula-generated list. To switch through the four contexts, select from the 1:Edit Page 4. You are now in edit-elements 5.
You are now in view-names context. You are now back in view-elements context. Remaining elements shift up one row. To insert a new element, press y 6. An ellipsis indicates that list elements continue beyond the screen.
In edit-elements context, you can attach a formula to a list name only if you Note: switched to it from view-names context. This lets you sort two-variable data on X and keep the data pairs together. The sorted lists are updated in memory. You can specify zero to 20 Additionally, if you want to use will automatically unarchive the time.
