"Candidate Brown leads the poll with 51% of the vote. Candidate Jones has 42% approval, and the remaining 7% are undecided. This poll was taken from a sample of registered voters and has a margin of error of plus-or-minus 4 percentage points" (Gravetter & Wallnaue, 2009, p. 7). We now know that the margin of error is the sampling error. What specifically does it mean that this example has a margin of error of plus-or-minus 4 points? How might you consider this information as far as how close the race is?
