These are average
Math SAT scores by
county. We despise
using measures like
geographical area
averages. Nor are we
statistically very fond
of the Math SAT
scores. Once again,
we've lost the
dropouts as well as
students who took
only the ACT or who
took neither test. Still,
the Math SAT scores
correlate reasonably
well with other SAT
scores and with most
other tests. Do they
accurately predict
success in college and
One gets 200 just to sign one's name. After excluding Alpine (no
scores this year) the state average is 512 - not significantly above the
theoretical average of 500. The standard deviation, which measures
how much variation there is among these county average mathematics
SAT scores, is 32.
