Margin Error Formula
margin of sampling error is a statistically proven number based on the size of the sample group [source: American Association for Public Opinion Research].

Polls | 2 comments Presidential Polling's Margin for Error by Rebecca Goldin | Oct 14, 2015 | Margin of error, Polls | 2 comments Polls are finding Donald Trump ahead—way ahead—of other candidates running for http://www.stats.org/presidential-pollings-margin-for-error/ the Republican nomination for presidency. Based on a recent Pew Research Center poll, CNN http://www.dictionary.com/browse/margin-of-error practically declared victory for him, noting he got 25 percent of the votes in the survey. The Daily News wrote off Jeb Bush—pointing to his 4 percent support rate. Ben Carson came in at 16 percent; Carly Fiorina and Marco Rubio won 8 percent.

It doesn’t measure most kinds of errors that plague many polls and surveys, like biased questions or selecting survey respondents in a way that’s not random. MOE does not measure a mistake, either. When a random sample of all Republicans is taken—a small group of people meant to be chosen randomly from all the possible likely Republican voters—there is always a possibility that the opinions of those in this sample don’t reflect those of the whole population. The MOE is a measurement of how confident we can be that such a survey of the opinions of a small number of people actually reflects the opinions of the whole population.
