Margin of error is calculated from a number of variables: your desired precision (which is known as the confidence level and is typically 95%), your sample proportion, and your sample size. In this specific example, the margin of error calculation is especially valuable because it shows us that the people who prefer this product may not actually be in the majority. Putting this into practice, if researchers estimate that 52% of people prefer a certain product with a +/-3 percentage point margin of error at a desired confidence level of 95%, the actual percentage of people in the overall population who prefer the product is between 49% and 55% 95 times out of 100. A smaller margin of error is better as it suggests the survey’s results are more precise. Margin of error is used in research to determine the precision of a result, such as a poll, survey, or a scientific study.Įxpressed as +/- percentage points, margin of error tells you to what degree your research results may differ from the real-world results, revealing how different – more and less – the stated percentage may be from reality.
