The margin of error is a statistic expressing the amount of random sampling error in the results of a survey. The larger the margin of error, the less confidence one should have that a poll result would reflect the result of a census of the entire population. The margin of error will be positive whenever a population is … See more Consider a simple yes/no poll $${\displaystyle P}$$ as a sample of $${\displaystyle n}$$ respondents drawn from a population $${\displaystyle N{\text{, }}(n\ll N)}$$ reporting the percentage $${\displaystyle p}$$ of … See more If a poll has multiple percentage results (for example, a poll measuring a single multiple-choice preference), the result closest to 50% will … See more The formulae above for the margin of error assume that there is an infinitely large population and thus do not depend on the size of population $${\displaystyle N}$$, but only on the … See more • Sudman, Seymour and Bradburn, Norman (1982).

WebJun 7, 2024 · If the MOE is under 12% of the estimate, it is considered highly reliable. If it is between 12 and 40% it is considered medium reliability, and anything over 40% is considered low reliability.
