Margin Of Error And Confidence Interval. The margin of error is. A margin of error tells you how many percentage points your results will differ from the real population value. A confidence interval is the likely range for the true score of your entire population. 95 confidence interval 125 185 The width of the confidence interval is 185 125 6.
Larger the sample the narrower the confidence interval or margin of error. The Margin of Error MOE is calculated according to the formula. Abstract Confidence interval estimation is a fundamental technique in statistical inference. Margin of error is used to delimit the error in estimation. For example suppose we have the following confidence interval for a population mean. Although the term is widely used to report the results of survey research in statistics the margin of error is usually expressed as a confidence interval.

For example suppose we have the following confidence interval for a population mean.
