Error Margin

Error Margin, often referred to as Margin of Error, is the estimated range within which the true value of a measurement is expected to fall. It acknowledges that every research study, survey, forecast, or statistical estimate contains some degree of uncertainty due to sampling variation, measurement limitations, response variability, or methodological constraints.

A smaller Error Margin generally indicates greater precision, assuming the research has been conducted appropriately. However, precision alone does not guarantee accuracy. A highly precise estimate may still be misleading if the research design contains systematic bias or if the underlying assumptions are incorrect.

Error Margin should always be interpreted alongside sample size, confidence level, research methodology, and data quality rather than as an isolated indicator of reliability.
