This simple margin of error (MOE) calculator can be employed to compute the MOE of a survey in accordance with the sample proportion and size, and the desired confidence level.
Margin of Error Calculator. Enter the confidence level, sample size, sample proportion, and population size to find the margin of error using the calculator below. Confidence Level: Sample Size: Proportion of the sample with the characteristic of interest. Sample Proportion: % Population Size: optional. Margin of Error: Steps to Solve.
Calculator to compute the confidence interval or margin of error of a sample based on the desired confidence level. It also provides an error bar diagram.
The margin of error gives a range of values around a survey estimate, showing the level of uncertainty. For example, if a survey says 60% support a policy with a margin of error of ±4% at a 95% confidence level, we're reasonably confident the true support level falls between 56% and 64%.

The margin of error (MOE) for a survey tells you how near you can expect the survey results to be to the correct populationvalue. For example, a survey indicates that 72% of respondents favor Brand A over Brand B with a 3% margin of error. In this case, the actual population percentage that prefers Brand A likely falls within the range of 72% ± 3%,...
Like confidence intervals, the margin of error has a confidence level. Different random samples drawn from the same population are likely to produce slightly different estimates. If you draw many random samples and calculate a margin of error around each estimate, a percentage of those ranges will contain the population value. Confidence levels are...
In a survey, the size of the margin of error varies depending on the percentage. Surveys frequently cite its maximum MOE. That’s the value you’ll see in the media when they report a survey’s margin of error. Knowing this value is beneficial because the margins of error for all percentages in a survey will not exceed this value. The largest margin o...
Surveys frequently use proportions and percentages in their results. For example, 92% agree with a particular decision. Consequently, the margin of error formula for surveys relates to percentages. When you add and subtract the MOE from the survey proportion, you obtain a confidence interval of the proportion. In statistics, most margin of error/co...
The margin of error only accounts for random sampling error. It cannot factorin wording biases, non-representative samples, difficulties that exclude particular types of respondents, etc. Additionally, these MOEs are for individual percentages and not the differences between responses. For example, suppose 51% of respondents prefer Candidate A and ...
Margin of Error represents the uncertainty in a statistical measurement, reflecting the extent to which the results could vary due to sampling error. How do I interpret Margin of Error in polls? A smaller Margin of Error indicates higher confidence in the poll’s results reflecting the true population values.

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. Margin of error (statistic) = Critical value x Standard error of the sample. How to Calculate Margin of Error: Steps
