Margin of error is a statistical measure that expresses the amount of random sampling error in survey results. It indicates the range within which the true population value likely falls.
Margin of error helps interpret poll accuracy and understand the uncertainty in survey results, preventing overconfidence in small differences between candidates.
Margin of error doesn't account for all types of errors—only random sampling error, not systematic biases or methodological problems.
