I hear people loughing at this phrase and its variations.
In principal, there is nothing contradictory in the statement itself.
It is clear to everybody who knows the basics of statistics
(at the level of definition of "average", which for a distribution is
the same as an arithmetic mean).
As a matter of fact, depending on the distribution you can get any
number (percentage) X , 0% < X < 100% that can be above (or below)
average.
If it is unclear, a simple example can demonstrate it.
Imagine in a class of 100 students, 99 students getting 100% score,
and one student getting a smaller score, say, 99%.
99% of students will have their score above average, because average
will be below 100%.
One should not mix average (arithmetic mean) and median.

Well stated, Igor! Thanks...
