Entering data

Applications numbered 1, 2, and 4 in the list above require that the data
be available as columns of the matrix DAT. One way this can be
accomplished is by entering the data in columns using the Matrix Writer,
„² , and then using function STO to store the matrix into DAT.
For example, enter the following data using the Matrix Writer (see
Chapters 8 or 9 in this guide), and store the data into DAT:
2.1 1.2 3.1 4.5 2.3 1.1 2.3 1.5 1.6 2.2 1.2 2.5.
The screen may look like this:
Notice the variable @£DAT listed in the soft menu keys.
A simpler way to enter statistical data is to launch a statistics application
(such as Single-var , Frequencies or Summary stats , see
first screenshot above) and press #EDIT# . This launches the Matrix Writer.
Enter the data as before. In this case, when you exit the Matrix Writer, the
data you have entered is automatically saved in DAT.
