What is the Margin of Error? The margin of error (MOE) for a survey tells you how near you can expect the survey results to be to the correct population value. For example, a survey indicates that 72% of respondents favor Brand A over Brand B with a 3% margin of error.
The margin of error can be calculated in two ways, depending on whether you have parameters from a population or statistics from a sample: Margin of error (parameter) = Critical value x Standard deviation for the population.

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.
Aug 21, 2024 · The margin of error is a statistical expression used to calculate the percentage point by which the result differs from the entire population's value. It is calculated by dividing the population's standard deviation by the sample size and multiplying the result by the critical factor.
May 13, 2022 · We use typically use margin of error when calculating confidence intervals for population parameters. The following examples show how to calculate and interpret margin of error for a population proportion and a population mean.
Mar 8, 2023 · The Margin of Error (MoE) is a statistical concept that helps to measure the uncertainty of a survey or poll result. It is typically expressed as a percentage or number. Surveys and polls are usually based on samples, which are smaller groups selected from the larger population.
Margin of Error: ±3.099%. The Margin of Error (MOE) is calculated according to the formula: MOE = z * √p * (1 - p) / √n. Where: z = 1.96 for a confidence level (α) of 95%, p = proportion (expressed as a decimal), n = sample size. z = 1.96, p = 0.5, n = 1000.
