Explorations in statistics: standard deviations and standard errors
"A standard deviation estimates the variability among sample observations whereas a standard error of the mean estimates the variability among theoretical sample means."
Standard deviations and standard errors
"if we want to say how widely scattered some measurements are, we use the standard deviation.
If we want to indicate the uncertainty around the estimate of the mean measurement, we quote the standard error of the mean."
Statistical notes for clinical researchers: Understanding standard deviations and standard errors.
"The distinction between standard error and standard deviation is not easy to explain. Confusingly, standard error itself is a kind of standard deviation. However the fundamental difference between a standard deviation and a standard error is that the former is used in a descriptive purpose while the latter is used in an inference procedure, in which information regarding samples is used to make explanations about populations."
