engineering, see Tolerance (engineering). For the eponymous movie, see Margin for error (film). The top portion charts probability density against actual percentage, showing the relative probability that the actual margin of error definition statistics percentage is realised, based on the sampled percentage. In the bottom portion, each margin of error examples line segment shows the 95% confidence interval of a sampling (with the margin of error on the left, and confidence interval definition unbiased samples on the right).

a survey's results. It asserts a likelihood (not a certainty) that the result from a sample is close to the number one would get if the whole population had been queried.
