16. Reason for weighting
If you randomly dial listed numbers and ask who they vote for for president and 90% of respondents say "John Kerry" and 9% say "Ralph Nader" and 1% say "Dubya" and then you ask what party they belong to and 75% of the 90% who said Kerry answer "Democrat" and 100% of the 9% who voted for Ralph say "Throw My Vote Aways" then you can safely surmise that the 1% who voted "Dubya" have an IQ of the same value as their percentage of votes.

Seriously though. If you poll 3500 people and 3400 say Kerry but all 3400 are registered Democrats through sheer chance, you have to weight the results or the poll doesnt accurately reflect the data.
