when you put the data in the calc, does it have to be in order?

@icsk8freak No, the data does not need to be in any particular order to use this function. The 1-Var Stats will still give you the five number summary (min, Q1, med, Q3, max) without the entered data being in order.

Though there is no need to order for 1-Var Stats, there is a separate function you can use if you want to order your data, after you've entered data into, say, L1. Do Stat > SortA(L1) > Enter, and it will sort L1 in ascending order. SortD will sort in descending order.
