I'm reluctant to answer your question because it sounds too much
like doing your homework but I would have no qualms about answering
a more specific question of the form "How do I get PSPP to do X?"
where X is a specific thing, like testing whether two means are
significantly different or estimating the linear relationship
between two variables. Or a question like "How do I structure the
data to do X?" where X is a PSPP statistical routine.
If you need help deciding what to do with the data, I think you
would learn more by discussing this with your professor, TA or a
classmate than having someone suggest something. You might also
find it helpful to google for similar problems and see what others
have done to solve it.
And finally, I think packages like PSPP, SPSS, etc. are best when
you have a specific statistic or hypothesis test that you are trying
to compute. But your problem does not fit into that mould. You
have a mass of semi-structured data that you are trying to make
sense. You might find that what you really want is a visualization
and I hate to say it but R might be a better package for this
purpose.

Hi
I need to use PSPP to analyse some data for a report I need to write for a
course but I'm having trouble matching up what I want to do with what PSPP
is capable of doing. I want to analyse the use of tags on a weblog over a
period of years, frequency of each tags use and some sort of representation
of the use of each tag over time. Below is a very simple representation of
my data in PSPP. Posts listed on the left column, then date of post and
then codings for tags (if a tag is used 1, if not used 0):
Post Names date tag1 tag2 tag3
--------------------------------------------------------------
Post 1 12-AUG-2013 1 0 1
Post 2 19-JUN-2013 0 0 1
Post 3 06-MAY-2013 1 1 0
How can I show the use of the tags over time - what analysis should I be
focusing on? Perhaps I'm structuring my data all wrong and should be
putting tags in the left column with simply a post count after date? Like
so:
Tag Names date Post Count
-------------------------------------------------
Tag1 12-AUG-2013 2
Tag2 19-JUN-2013 1
Tag3 06-MAY-2013 2
Any help much appreciated.
