Agreed.  I thought that was odd too.  I hoped the OP might work out that
something was wrong after looking at the data file used for the UCLA
example.  Here's a relevant excerpt that should give a pretty good hint:

--- start of excerpt ---

Description of the data

Let’s pursue Example 1 from above.

We have attendance data on 314 high school juniors from two urban high
schools in the file
https://stats.idre.ucla.edu/wp-content/uploads/2016/02/nb_data.sav.  The
response variable of interest is days absent, daysabs.  The variable math is
the standardized math score for each student.  The variable prog is a
three-level nominal variable indicating the type of instructional program in
which the student is enrolled.

Let’s look at the data.  It is always a good idea to start with descriptive
statistics and plots.

    get file
"https://stats.idre.ucla.edu/wp-content/uploads/2016/02/nb_data.sav".
    descriptives variables = daysabs math.

I assumed the OP knows that variable = column in SPSS.
