Standard deviation is considered the most appropriate measure of variability when using a population sample, when the mean is the best measure of center, and when the distribution of data is normal. Some argue that average deviation, or mean absolute deviation, is a better gauge of variability w...
Relative Standard Deviation is defined as a parameter that describes the distribution of materials among each other, particularly in the context of tumble mixers. It is used to compare the current distribution to a desired value and adjust the mixer speed accordingly to achieve the optimal particle...
Table 4. Mean values of the EMPA analyses of the wollastonite NYAD G; standard deviation is shown in brackets. The chemical composition of wollastonite NYAD G given in the technical data sheet (TDS) provided by NYCO Minerals Inc. is shown for comparison [87]. Wt% (weight percent); Data ...
Standard Deviation of a Numerical Vector The population standard deviation a measures the spread of a vector in ℝn. It is defined to be the square root of the population variance of the vector. The sample standard deviation s is defined to the square root of the sample variance of the ...
The standard deviation is the statistic that measures the dispersion of some dataset relative to its mean value. It is also termed as the square root of the variance. It is computed as the square root of the variance by determining the variation between each data point with respect to the ...
the 1se rule in general does not necessarily provide a good estimation for the intended standard deviation of the cross validation error. The estimation bias can be 50–100% upwards or downwards in various situations; 2. the results tend to support that 1se rule usually outperforms the ...
Standard DeviationThe Standard Deviation is a measure of how spread out numbers are.Its symbol is σ (the greek letter sigma)The formula is easy: it is the square root of the Variance. So now you ask, "What is the Variance?"VarianceThe Variance is defined as:...
Lots about bell curves, 68%, and 95%, and something about the standard deviation being some kind of “measure,” but not a lot of crystal-clear definition. So let’s do it, right here: Definition of e e is defined as the number such that the curve y = ex is its own derivative ...

25) A popular term in Stylistics, ___, defined by Leech and Short as “artistically motivated deviation” involves all levels of language: vocabulary, sound, syntax, meaning, graphology, etc. 26) Where two syllables have the same initial and final consonants, but different vowels, they ___...
