- Only with a very liberal definition of "average" and "about 50%", or
- in case the quantity that's being averaged is symmetrically distributed
- around some value. It certainly is not *by definition* that 50% is
- less than average. By definition 50% is less than the median. This is
- not some theoretical point. The distribution of many important things
- is very skewed.

- Maybe newspapers should have a section in which concepts like "average",
- "mean", "modus", "standard deviation" and so on are explained every
- day. Just for the benefit of Mensa members that don't know their statistics.
