To create it, go to the Program Catalog view and press the key. Enter any name you want, such as
‘CCreate’. Now type in the code below. The program is set up to take a frequency table defined in columns
C8 and C9 and convert them into a single column stored in column C0. The program uses columns 8, 9 & 10
because there is seldom data in them.
We’ll now use this program to expand the frequency table I built earlier.
The first thing we need to do is to move columns
C1 and C2 to C8 and
C9. Rather than re-typing, this can be done in the HOME view as
shown.
the program
you created. Assuming that it has no errors you will see a running count
as it creates the new column. This is just to give you something to watch
while it works.
Now change into the
Program Catalogue and
If you then change to the
NUM view you will find that column C0
contains the result.
You can now import that column’s mean and standard deviation into the
Inference aplet. After you have used the column you will probably also
want to delete columns
C8, C9 and C0 to save space.
Bear in mind that if you use this program to create a column containing hundreds or even thousands of values
then the program will take a long time to complete. In the case of thousands of values you may even exceed
the calculator’s memory in the
MAKELIST command. It might be easier to use the Statistics aplet to calculate
the required mean and standard deviation in the normal way and then enter the values into the Inference aplet
either by hand or by using the
VARS menu.
