Let's use a simple example of how wrong you are, cary.
Question K09 on the 12th Grade TIMSS Math test given to 12th graders around
the world in 1995 reveals an astounding difference in math skills between
the sexes in all the countries who participated. The average difference in
all countries was 10.5%, with 47.3% of boys and 36.8% of girls answering
correctly, but the difference in the US was 22.1% (28.6% of girls and 50.7%
of boys). In countries like Cyprus where 60.1% of the boys answered
correctly, guesses on the test would not have influenced the scores by that
much, but where only 28.6% of American girls answered correctly, guesses
must be taken into account.
Since this was a multiple choice question with four possible choices, the
probability of getting the correct answer just by guessing is 25%. In other
words, for every four students who guessed, one of them would have gotten
the correct answer by chance. The maximum score would have been achieved
had all the students who didn't understand the problem guessed at the
answer, so where 28.6% of American girls answered the problem correctly,
23.8% of them got the correct answer by guessing, and 4.8% indicated that
they understood the problem [x = total guesses, 0.25x = correct guesses,
0.75x = incorrect guesses = 71.4%, x = 95.2%, 0.25x = 23.8%, 28.6% got the
correct answer - 23.8% guessed the correct answer = 4.8% understood the
problem]. However, with an estimated error of plus or minus 3%, only 1.8%
are known with certainty to have understood the problem.
American boys didn't do that much better, since [prior to the adjustment for
the 3% error] just 34.3% of them got the correct answer because they
understood the problem, 16.4% got the correct answer because they guessed,
and 49.3% guessed incorrectly. Thus only 31.3% are known with certainty to
have understood the problem.
Prior to adjustment for the 3% error, 53.2% of the boys in Cyprus guessed,
39.9% guessed incorrectly, 13.3% guessed correctly, and 46.8% understood the
problem [x = total guesses, 0.25x = correct guesses, 0.75x = incorrect
guesses = 39.9%, x = 53.2%, 0.25x = 13.3%, and 60.1% correct answers - 13.3%
correct guesses = 46.8% who understood the problem]. Only 43.8% are known
with certainty to have understood the problem, so per capita, compared to
American boys 40% more boys in Cyprus are known to have understood the
problem, and compared to American girls, 24 times as many were. Compared to
American girls, 17 times as many American boys are known to have understood
the problem.
Is this adequate proof that our attempt to establish "gender equality" is a
failure? Yes. To achieve that ephemeral goal, our "educators began an
unnecessary and destructive "gender war" of unprecedented proportions, more
than doubled education spending as a percent of GDP, and out-spent by more
than three times countries whose students far outperformed ours. Japan,
whose 8th graders scored 105 points higher than ours, spends half as much
for education. Korea, whose 8th graders scored 107 points higher than ours,
spends even less per student than Japan.
