how do I input data so that the TI-83 will rearrange the data in order?

Question

okay, so then what?

Answer 1

See the TI-83 manual in Chapter 12 : Statistics.  Put your data into a List, and use the "Stat List Editor".  Under the "Edit" heading, you will see the "SortA" and "SortD" which allow you to sort Ascending or Sort Descending the list contents.
