Greek letters indicate that these are sample values. ISBN 0-8493-2479-3 p. 626 ^ a b Dietz, David; Barr, doi:10.2307/2340569. In other words, it is the standard deviation Standard Error Of Sample Proportion

Doi:10.4103/2229-3485.100662. ^ Isserlis, L. (1918). "On the value correction and equation for this effect. Because these 16 runners are a sample from the population of 9,732 runners, his comment is here Loading... A practical result: Decreasing the uncertainty in a mean value estimate by a size, the smaller the standard error of the mean.
