# Calculating Single-variable Statistics - HP 49g+ User Manual

Graphing calculator.

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 ΣDAT use function STOΣ, available
through the catalog (‚N), e.g., STOΣ (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
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 STOΣ to store the data into ΣDAT.
