Entering Statistical Data

Data can be accumulated on the HP 48 in two different kinds

of objects: arrays and lists. In general, lists are best-suited for

one-variable statistics, arrays for multi-variable statistics. Arrays may

only contain numerical data; lists may contain any kind of data.

The built-in STAT application always uses arrays—specifically, it uses

the data currently stored in the array variable named EDAT.

However, to apply programmed statistical functions other t.han those

built into the STAT application, you may find lists are a more flexible

object type than arrays.

To enter statistical data as a list:

1. Press fi^lTT) to begin the list.

2. Type each datum followed by fSPC~). Press fENTER) after you’ve

typed the final datum.

3. Optional: Store the data list in a named variable in order to save

it for later use. Be careful not to store the list in an HP reserved

variable, such as EDAT.

To enter statistical data directly into EDAT:

1. Press

< to open the SI HGL..E--viiF< I FlBLE

S'iTi'TISTICS form. (Actually, you may use any of the STAT

application input forms.)

2. Optional: If there is already data in the SDfiTi: field either delete

it (press (del 1 OK ) or save the data by storing it in a variable

(see next procedure) first and then deleting it.

3. With the highlight on the field, press i£D

MatrixWriter (you may need to press fNXT) first).
