- Sorry, but by *one* of the definitions of "average", 50% of the
- population is indeed below average, since one meaning of "average"
- is median (others include mean and mode); it seems reasonable to
- conclude that that's the meaning the original poster was using. By
- "definition" I mean the sort of thing you can find in a dictionary
- of English; there may be fields that use "average" with a technical
- meaning, but I can't think of any at the moment.
