[SPSSX-L] calculating

First of all I need to know the words for that what
I mean. :)
Depending on the including criteria and the period I can say that
their are 100 possible observations for my research. But I only get 20
real observations (return of questionnaires).
>>>You might want to look at the Case Study
in the help for Direct Marketing > Identify top responding postal codes
to get some ideas.
What words would you use for the 20 person group and what for the 100
person group? Sample, population, ...? I am a little bit confused
about that. btw: If someone speak german please fill free to add the
german words, too. ;)
>>>Population and response rate.
If you set your output language to German, you can
see the German vocabulary used.
Now my SPSS question:
The 20 observations can be separated in (lets say) different companies.
I want to display/calculate how big is the part of each company on the
research.
The point is I want to display it for the real observations (20) and
for the possible ones (100), too.
For example there are 5 questionnaires from company A. This means a 25%
on the real observations and 5% on the possible ones. And if I know
e.g. that there are 30 possible observations in company A I can
calculate this, too.
The SPSS data of course doesn't know that there are 80 "missing"
observations.
Is there a easy SPSS-way to calculate and display that?
>>> The direct marketing study might help
here, but if you aggregate your data by company and enter the population
counts for the aggregate, you can calculate the response rates as a simple
COMPUTE.
btw: Of course I could do this myself etc. But maybe a statistic
package of such a feature in it?
