Definitions of Surveys and Public Opinion

|||||||||||||||||||||||||||
From the definition to the right, it can be seen that surveys
cannot be an actual representation of the public’s
opinion. What you are actually getting is a representative sample
that is supposed to be reflective of the entire population. As far as the poll
is concerned, your opinions have been taken into account, by someone just like
you. The essence of survey
sampling is that you don't actually have to interview everyone to get a good
idea of what everyone thinks. As long as everyone has an equal chance of being
included, we've created a "random" sample, which is the essence of
good survey design.
