On Using Standard Deviation or Standard Error of the Mean [PDF]
The mean value is commonly used as a measure of central tendency. It is frequently reported along with either the standard deviation (SD) or the standard error of the mean (SEM).

Estimating standard deviation via sample mean extended quantile estimation [PDF]
Background It is common practice in meta-analysis to estimate the mean and standard deviation (SD) when only the median and other ordered statistics are published in an included study. There are several methods for this purpose.

Transition Activity Recognition System Based on Standard Deviation Trend Analysis [PDF]
With the development and popularity of micro-electromechanical systems (MEMS) and smartphones, sensor-based human activity recognition (HAR) has been widely applied. Although various kinds of HAR systems have achieved outstanding results, there are still

Determining mean and standard deviation of the strong gravity prior through simulations. [PDF]
Humans expect downwards moving objects to accelerate and upwards moving objects to decelerate. These results have been interpreted as humans maintaining an internal model of gravity.

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

Standard deviation and standard error of the mean [PDF]
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.
