An opinion poll is an attempt to measure
public opinion by taking a survey of the
views of a representative sample of the
electorate, the science of opinion sampling
is called psephology. Most standard polls
take random samples of around a thousand
voters which gives results that should be
accurate to within three percentage points,
95% of the time.
