I wonder about the assignment, and "What does it mean?"
of the subject line.

As I recall from reading casually a few years ago, the
"meaning" of state-wide averages of SAT scores is
strongly influenced, if not dominated, by the selection
process of "who takes the test."

Flipping that question on it's head, one might ask, "What does it NOT
(necessarily) mean?" In other words, beware of the "ecological
fallacy". The Wikipedia page gives a good explanation. See
especially the "Origin of Concept" section.
