Maximum Allowable Error In Statistics


Definition[edit] The margin of error for a particular statistic of interest is usually defined as the radius (or half the width) of the confidence interval for that statistic.[6][7] The term can Rumsey When you report the results of a statistical survey, you need to include the margin of error.
