Statistically-speaking, 50% of ALL students must ALWAYS be below average
(and 50% above) - that's what 'average' means!

I heard that, despite years of effort and millions poured into our
public school system, fully 50% of our students still have a
less-than-average mastery of the science of statistics.

actually that's the definition of median. average can loosely (but not
properly) refer to mean, mode and median but properly average is just the
summation of all points divided by their number which may or may not have 50%
above and below. distributions are not always bell curves nor symmetric
about their average.

much more importantly, though, are you really that humour impaired? or is
this some clever bait? i hate that.

More accurately that's what "median" means. The "mean" is somewhat
different, and does not necessarily have equal numbers of samples
above and below it, even that's what most people think of when they
hear "average".

The "mean" can be skewed by outliers, such as when you try to find the
"average" income of people in the U.S.: the very rich people skew it
to a number which is higher than a true representation should be.
That's why they use "median" income and "median" house price data.

I don't think so. Approximately 50% must be below MEDIAN,
but not average. I say "approximately" because there may be
an odd number of students.

I could have some or all of that wrong.

The crassest thing I experienced was a woman who called somebody on her
mobile during a piano recital. That's right, she was not called, she did
the calling (and finally left when everybody else tried to kill her with
looks).
