It basically is the range of possible estimates generated by an estimating process that would, X% of the time (95% being the most commonly used) contain the true value of the
It does not represent other potential sources of error or bias such as a non-representative sample-design, poorly phrased questions, people lying or refusing to respond, the exclusion of people who could If there is a large overlap, then the difference is not significant (at the p <.05 level). Basic concept Polls basically involve taking a sample from a certain population. Difference Between Standard Error And Confidence Interval It should be: "These terms simply mean that if the survey were conducted 100 times, the actual percentages of the larger population would be within a certain number of percentage points

If you said (C), (D), or (E), remember that the interval [2.3, 3.1] has already been calculated and is not random.
Using statistical theory it is possible to say how precise a population estimate is by constructing a confidence interval around it to show the range of values which the true population Difference Between Sampling Error And Bias p.49. I love him so much he was everything to me without him my life is incomplete. So in this case, the absolute margin of error is 5 people, but the "percent relative" margin of error is 10% (because 5 people are ten percent of 50 people).

Our conclusion was that you need to be clear what you mean by "margin of error" whenever you use that term. news Sampling theory provides methods for calculating the probability that the poll results differ from reality by more than a certain amount, simply due to chance; for instance, that the poll reports The likelihood of a result being "within the margin of error" is itself a probability, commonly 95%, though other values are sometimes used. Suppose you decide that you want to refine your estimate of the population proportion and cut the width of your interval in half. Difference Between Margin Of Error And Confidence Interval
