Standard deviation and standard error of the mean [PDF]

open access: yesKorean Journal of Anesthesiology, 2015
In most clinical and experimental studies, the standard deviation (SD) and the estimated standard error of the mean (SEM) are used to present the characteristics of sample data and to explain statistical analysis results.

STATISTICS OF THE MEAN DEVIATION METER

open access: yesCanadian Journal of Physics, 1952
The mean deviation is evaluated for a number of distributions of a Poisson or similar type, such as arise with counters, scaling circuits, and in particular with the mean deviation meter described by Greenberg and Happ.

Introducing the mean absolute deviation ‘effect’ size

open access: yesInternational Journal of Research and Method in Education, 2015
This paper revisits the use of effect sizes in the analysis of experimental and similar results, and reminds readers of the relative advantages of the mean absolute deviation as a measure of variation, as opposed to the more complex standard deviation ...

Mean-standard deviation-conditional value-at-risk portfolio optimization [PDF]

open access: yesMathematics and Modeling in Finance, 2023
The use of variance as a risk measure is limited by its non-coherentnature. On the other hand, standard deviation has been demonstrated as acoherent and effective measure of market volatility. This paper suggests theuse of standard deviation in portfolio
