Calculating Single-Variable Statistics - HP 50g User Manual

Store the program in a variable called LXC. After storing this program in RPN
mode you can also use it in ALG mode.
To store a column vector into variable DAT use function STO , available
through the catalog (‚N), e.g., STO (ANS(1)) in ALG mode.
Example 1 – Using the program LXC, defined above, create a column vector
using the following data: 2.1 1.2 3.1 4.5 2.3 1.1 2.3 1.5 1.6 2.2
1.2 2.5.
In RPG mode, type in the data in a list:
{2.1 1.2 3.1 4.5 2.3 1.1 2.3 1.5 1.6 2.2 1.2 2.5 } `@LXC
Use function STO to store the data into DAT.
Note: You can also enter statistical data by launching a statistics application
(such as Single-var, Frequencies or Summary stats) and
pressing #EDIT#. This launches the Matrix Writer. Enter the data as you usually
do. In this case, when you exit the Matrix Writer, the data you have entered is
automatically saved in DAT.
