This roughly means that 95 percent of the time, the survey estimate should be within three percentage points of the true answer.If 54 percent of people support Hillary Clinton, the survey estimate might be as high as 57 percent or as low as 51 percent, but it is http://www.nytimes.com/2016/10/06/upshot/when-you-hear-the-margin-of-error-is-plus-or-minus-3-percent-think-7-instead.html unlikely to be 49 percent. This truism of modern polling, heralded as one of the great success stories of statistics, is included in textbooks and taught in college classes, including our own.But the real-world margin of error of election polls is not three percentage points. It is about twice as big.In a new paper with Andrew Gelman and Houshmand Shirani-Mehr, we examined 4,221 late-campaign polls — every public poll we could find — for 608 state-level presidential, Senate and governor’s races between 1998 and 2014. Comparing those polls’ results with actual electoral results, we find the historical margin of error is plus or minus six to seven percentage points. (Yes, that’s an error range of 12 to 14 points, not the typically reported 6 or 7.)

Designed for the novice, Polling Fundamentals provides definitions, examples, and explanations that serve as an introduction to the field of public opinion research. Total Survey Error What is meant by the margin margin of error of error? Most surveys report margin of error in a manner such as: "the results of this survey are accurate at the 95% confidence level plus or minus 3 percentage points." That is the error that can result from the process of selecting the sample. It suggests what the upper and lower bounds of the results are. Sampling error is the only error that can be quantified, but there are many other errors to which surveys are susceptible. Emphasis on the sampling error does little to address the wide range of other opportunities for something to go wrong. Total Survey Error includes Sampling Error and three other types of errors that you should be aware of when interpreting poll results: Coverage Error, Measurement Error, and Non-Response Error. What is sampling error? Sampling Error is the calculated statistical imprecision due to interviewing a random sample instead of the entire population. The margin of error provides an estimate of how much the results of the sample may differ due to chance when compared to what would have been found if the entire population was interviewed.
