Compute the margin of error (MOE) of a survey based on sample proportion, size, and confidence level. Learn the formula, see examples, and find out how to estimate the sample size.
20 gru 2021 · This calculator calculates the margin of error for surveys based on sample size and proportion. It also allows you to set the desired level of confidence.
Learn how to find margin of error and use the online calculator to measure it. The margin of error shows how much sample results may differ from the whole population and depends on sample size, population standard deviation, and confidence level.
Calculate the margin of error for surveys with or without finite population correction using this free online tool. Enter the sample size, population size, sample proportion, and confidence level to get the MOE formula and solution.
Try our Margin of Error Calculator. Input your survey data into our easy-to-use calculator, or experiment with the numbers to see how they impact margin of error. If you want to learn how margin of error is calculated, skip ahead to our breakdown of the margin of error formula.
An acceptable margin of error used by most survey researchers typically falls between 4% and 8% at the 95% confidence level. It is affected by sample size, population size, and percentage. *This margin of error calculator uses a normal distribution (50%) to calculate your optimum margin of error.
