Margin of Error is an estimate of how far true population values may be from the collected sample data. It is generally expressed in percentage points and depends on the size of your Target Market, Sample Size, and the Confidence Level.
Simply put, you want to have the lowest possible Margin of Error, at the highest possible Confidence Level.
You can use this calculator in two ways; to determine margin of error on a completed survey, or to determine the required sample size for a study, depending on your target margin of error.
