Yes, we could really use a "getting started" guide, and some
examples.  PSPP was originally targeted at existing users of SPSS
but we do seem to getting some new users who have never used

That's typical.

You'd have to decide how to distinguish the groups.  I suspect
you'd have two variables: "animals" and "score", and you'd want a
syntax file that looks something like this:

data list /animal 1-5(a) score 7-8.
begin data.
tiger 9
tiger 24
tiger 32
tiger 11
tiger 19
other 24
other 24
other 32
other 48
end data.

Then you could get, say, descriptive statistics on each group
like so:

split file by animal.
descriptives score.
