Misuderstanding statistics. If only 10% of a population is under 25, yet 35% of a films audience is under 25...
...It means that a high pecentage of under 25's are in the audience.
It's been ages since I did statistics, so I can't really explain better than that. Maybe someone else will pick up on it.
We have a winner!
That link is actually saying the opposite to what it thinks it's saying - the movie is above-quota popular with the
under 25s, not the
over 25s. Under 25's make up about 30% of the population of the US, so are over representing themselves at
Star Trek by 5%. Conversely, over-25s are under-represented. However, the
point still stands - the movie si clearly
popular with the over-25 crowd, so worries about 'aiming it at teenagers' etc are clearly unfounded.
