"differ".
You're right. Then the tense would be consistent with that of the
previous clause.
I notice that @footnote is not used in quite the right way in a few
places.
In particular, there should be no space between the text and the @footnote
command; otherwise there is a space between the text and the footnote
marker
in the output, which is not the usual style.
OK. I'll fix that.

Is this correct? I would have guessed that it assumes that it assumes that
it is *not* already proven.
There are three possibilities: A < B, A == B, or A > B. Often,
however, the event A < B common sense tells us cannot be true, and
the researcher can dismiss this possibility. If we know that A < B
(or B < A) cannot be true, then a one tailed test can be used instead
of a two tailed test, thus doubling the power of the test.
For example, in an experiment involving animals exposed to some
radiation treatment, A might be the mean radiation from the cells of
the exposed animals, and B the mean of the cells from the control group.
Regardless of whether I'm right about that, "is it" => "it is".
I'll fix that.
As I continue to read through examples, I find myself wondering whether
there
is value in inserting the @prompt{PSPP>} prefixes. Since these appear on
(almost) every line, they don't really teach the reader very much, and they
make it more difficult to cut-and-paste from the manual.
You could well be right. Maybe it only needs the prompt for the first
few examples.
