Task: Question Answering
Input (English): passage: The margin of error is usually defined as the ``radius'' (or half the width) of a confidence interval for a particular statistic from a survey. One example is the percent of people who prefer product A versus product B. When a single, global margin of error is reported for a survey, it refers to the maximum margin of error for all reported percentages using the full sample from the survey. If the statistic is a percentage, this maximum margin of error can be calculated as the radius of the confidence interval for a reported percentage of 50%.
 question: is margin of error the same as confidence interval?
Output (English): No
