On Using Standard Deviation or Standard Error of the Mean [PDF]

open access: yesIranian Journal of Medical Sciences
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]

open access: yesBMC Medical Research Methodology
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]

open access: yesSensors, 2020
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

Terrain Irregularity Sensing by Evaluating Feet Coordinate Standard Deviation [PDF]

open access: goldApplied Sciences
Locomotion over rough terrain is still a problem yet to be solved for legged robots. One of the problems arises from the inability to identify terrain roughness during locomotion, which could be crucial for decision-making and successful task completion.

Standard deviation: Standardized bat monitoring techniques work better in some ecosystems. [PDF]

open access: yesPLoS ONE
Standardized monitoring strategies are often used to study spatial and temporal ecological patterns and trends. Such approaches are applied for many study taxa, including bats (Mammalia, Chiroptera).

Determining mean and standard deviation of the strong gravity prior through simulations. [PDF]

open access: yesPLoS ONE, 2020
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]

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

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.

Locally structured correlation (LSC) plots describe inhomogeneity in normally distributed correlated bivariate variables

open access: yesArchives of Public Health, 2022
Background The association between bivariate variables may not necessarily be homogeneous throughout the whole range of the variables. We present a new technique to describe inhomogeneity in the association of bivariate variables. Methods We consider the
