Statistical Applications
The calculator provides the following pre-programmed statistical features
accessible through the keystroke combination
‚Ù (the 5 key):
Entering data
Applications numbered 1, 2, and 4 in the list above require that the data
be available as columns of the matrix ΣDAT. One way this can be
accomplished is by entering the data in columns using the Matrix Writer,
„², and then using function STOΣ to store the matrix into ΣDAT.
For example, enter the following data using the Matrix Writer (see
Chapters 8 or 9 in this guide), and store the data into ΣDAT:
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 ΣDAT.
