How to standard error

WebStandard errors provide simple measures of uncertainty in a value and are often used because: in many cases, if the standard error of several individual quantities is known then the standard error of some function of the quantities can be easily calculated; WebOct 10, 2005 · The standard error of the sample mean depends on both the standard deviation and the sample size, by the simple relation SE = SD/√(sample size). The standard error falls as the sample size increases, as the extent of chance variation is reduced—this idea underlies the sample size calculation for a controlled trial, for example.
