smaller the margin of error. The margin of error is a statistic expressing the amount of random sampling error in 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. The likelihood of

a result being "within the margin of error" is itself a probability, commonly 95%, though other values are sometimes used. The larger the margin of error, the less confidence one should have that the poll's reported results are close to the true figures; that is, the figures for the whole population. Margin of error applies whenever a population is incompletely sampled. Margin of error is often used in non-survey contexts to indicate observational error in reporting measured quantities. In astronomy, for example, the convention is to report the margin of error as, for example, 4.2421(16) light-years (the distance to Proxima Centauri), with the number in parentheses indicating the expected range of values in the matching digits preceding; in this case, 4.2421(16) is equivalent to 4.2421 ± 0.0016.[1] The latter notation, with the "±", is more commonly seen in most other science and engineering fields.

Previous margin of error vs standard error Thread Next Thread Loading... lapot Senior Member Zaragoza (España) Español Hello. I've got a doubt about this common sentence. I've always heard "margin of error", but https://en.wikipedia.org/wiki/Margin_of_error the last time I heard this sentence, it was "margin for error". Well, then I searched in google and I found it was more common than I ever thought. So, please, is there any difference between them? Both are correct? I don't give any context because my question is in general. Cheers! lapot, http://forum.wordreference.com/threads/margin-of-for-error.1680750/ Jan 27, 2010 #1 entangledbank Senior Member London English - South-East England Without looking at the Google results (which could easily prove me wrong) I would think that the difference is that 'margin of error' is a simple noun phrase, where 'of error' tells you what kind of margin it is: The margin of error is 5%. We were surprised at the margin of error. Such a large margin of error is unacceptable. But 'margin for error' is two separate parts, and would be somewhat unlikely to appear in the above sentences. I personally would use it in existential sentences ('there is . . .') where 'for error' explains the purpose/reason of the margin, and can be replaced by similar phrases: There is a very large margin for error. There is a very large margin by which we can go wrong. There is a very large margin for getting it wrong. Go on, Google, do your worst. en

Rumsey When you report the results of a statistical survey, you need to include the margin of error. The general formula for the margin of error for a sample proportion (if certain conditions are met) is where is the sample proportion, n is the sample size, and z* is the appropriate margin of error z*-value for your desired level of confidence (from the following table). z*-Values for Selected (Percentage) Confidence Levels Percentage Confidence z*-Value 80 1.28 90 1.645 95 1.96 98 2.33 99 2.58 Note that these values are taken from the standard normal (Z-) distribution. The area between each z* value and the negative of that z* value is the confidence percentage (approximately). For example, the area between z*=1.28 and z=-1.28 is approximately 0.80. Hence this chart can be expanded to other confidence percentages as well. The chart shows only the confidence percentages most commonly used. Here are the steps for calculating the margin of error for a sample proportion: Find the sample size, n, and the sample proportion. The sample proportion is the number in the sample with the characteristic of interest, divided by n. Multiply the sample proportion by Divide the result by n. Take the square root of the calculated value. You now have the standard error, Multiply the result by the appropriate z*-value for the confidence level desired. Refer to the above table for the appropriate z*-value. If the confidence le
