What is Margin of error?
The '''margin of error''' is a way to measure the [[sampling error]] in the results of a [[statistical survey]]. A bigger margin of error means that the results are less certain. Margins of error occur when a [[population]] is incompletely sampled. Usually, the margin of error is defined as the radius (half the width) of a [[confidence interval]] for a given sample. {{stub}} [[Category:Errors and residuals in statistics]]
