> How Can There Still Be a Sex Difference, Even When There Is No Sex Difference?
Really the article explains how
on some measure two populations
can have the same average on the
measure but still be different.
The answer is obvious: The two
distributions are different,
e.g., the two standard deviations
can be different.
Not mysterious.
But the stuff in the article about
human female brains and calico cats
is really nice to know.
But the article is one in a
series, and one of the articles
there, maybe the next one,
discusses how the distribution
and mean of number of children
per person is different
for men and women. Okay.
But the article has some
graphs of distributions, and,
very sadly, insists on
drawing the distributions
as bell curves. Yup,
bell curves and in particular
Gaussian densities were swallowed
whole at about 1930
by much of
the social sciences and
educational statistics
and is often still
accepted.
