The 2 sigma of a standard deviation also gives you a range of ~95%. Can someone shed some light on how they are different? confidence-interval standard-deviation share|improve this question edited May 9 '15 at 11:54 http://stats.stackexchange.com/questions/151541/confidence-intervals-vs-standard-deviation Andy 11.7k114671 asked May 9 '15 at 11:43 Berry 6112 add a comment| 2 Answers 2 active oldest votes up vote 4 down vote There are two things here : The "2 sigma rule" where sigma refers to standard deviation is a way to construct tolerance intervals for normally distributed data, not confidence intervals (see this link to learn about the difference). Said shortly, tolerance intervals refer to the distribution inside the population, whereas confidence intervals refer to a degree of certainty regarding an estimation. In case you meant standard error instead of standard deviation (which is what I understood at first), then the "2 sigma rule" gives a 95% confidence interval if your data are normally distributed (for example, if the conditions of the Central Limit Theorem apply and your sample size is great enough). share|improve this answer edited May 9 '15 at 15:57 answered May 9 '15 at 12:23 Antoine R 485311 2 This doesn't appear to address the question itself, which asks for the distinction between a confidence interval and a "2 sigma ... range" (which is something that is closer to a tolerance interval). –whuber♦ May 9 '15 at 13:18 That's not how I unders
the standard error can be calculated as SE = (upper limit – lower limit) / 3.92. http://handbook.cochrane.org/chapter_7/7_7_7_2_obtaining_standard_errors_from_confidence_intervals_and.htm For 90% confidence intervals divide by 3.29 rather than 3.92; for 99% confidence intervals divide by 5.15. Where exact P values are quoted alongside https://www.youtube.com/watch?v=HxH7Ze9LN_w estimates of intervention effect, it is possible to estimate standard errors. While all tests of statistical significance produce P values, different tests use different confidence interval mathematical approaches to obtain a P value. The method here assumes P values have been obtained through a particularly simple approach of dividing the effect estimate by its standard error and comparing the result (denoted Z) with a standard normal distribution (statisticians often refer to this as a Wald test). error confidence interval Where significance tests have used other mathematical approaches the estimated standard errors may not coincide exactly with the true standard errors. The first step is to obtain the Z value corresponding to the reported P value from a table of the standard normal distribution. A standard error may then be calculated as SE = intervention effect estimate / Z. As an example, suppose a conference abstract presents an estimate of a risk difference of 0.03 (P = 0.008). The Z value that corresponds to a P value of 0.008 is Z = 2.652. This can be obtained from a table of the standard normal distribution or a computer (for example, by entering =abs(normsinv(0.008/2) into any cell in a Microsoft Excel spreadsheet). The standard error of the risk difference is obtained by dividing the risk difference (0.03) by the Z value (2.652), which gives 0.011.
