The margin of error (moe) is a statistic that indicates the amount of sampling error in the sample statistic, such as the mean. Learn what margin of error is, when it should be used and what affects it. A margin of error tells you how many percentage points your results will differ from the real population value. Without it even the most promising results can be misleading.
For example, a 95% confidence interval with a 4 percent margin of error. It tells the variance from the actual population in terms of the percentage points. In the world of survey research understanding the margin of error isn’t just a nice to have; When essential business decisions are being made using survey data, you need to know if that data is.
The margin of error (moe) for a survey tells you how near you can expect the survey results to be to the correct population value.
