The Omnibus Company’s Margin of Error Calculator determines the amount of random variation in any survey result.  This variation is used to account for any differences between your survey results and the true opinions of the audience you are sampling. 

Margin of error is also a standard measure for understanding the random variation you might see if the exact same survey was conducted multiple times.  In other words, a survey with a 3% margin of error has results that could vary by as much as 3% in either direction each time the study was conducted.  Generally, the margin of error is rarely smaller than 3% for survey results.  In any survey, a lower margin of error means higher confidence in your results.

The percentage expressed by the Omnibus Company’s calculator determines your margin of error at the 95% confidence level for a study conducted among a random sample, or a probability sample.  This mean that 95% of the time, your survey results are accurate within the range determined by this calculator.
