Question

Quizplus · Accepted Answer

The margin of error in a confidence interval is calculated to account for the random sampling errors. It is the measure of the uncertainty in the estimation process, which is a result of the limited sample size used to represent the population. Undercoverage, nonresponse or design errors do not directly account for the margin of error, although they can affect the accuracy of the estimation.
