| Domain | Definition |
Aerospace | A measure of the dispersion of data points around their mean value. It is the positive square root of the arithmetic mean of the squares of the deviation from the arithmetic mean of the population: where m is arithmetic mean; d is deviation from the arithmetic mean; and n is number of points.Symbol s.

Biology & Biotechnology | The mean scatter of a population of numbers from the population mean(a). The square root of the variance(b). Source: European Union. (references) |
Census | A measure which shows the average variability in population from the mean. It is defined as the square root of the variance. (references) |
Electrical Engineering | The positive square root of the variance. Source: European Union. (references) |
Geological | How much a set of data is different from the curve it should make when plotted on a graph. Or, the square root of the average of the squares of deviations about the mean of a set of data. Standard deviation is a statistical measure of spread or variability. (references) |

(From Wikipedia, the free Encyclopedia)
In probability and statistics, the standard deviation, generally denoted σ ('sigma'), is the most commonly used measure of statistical dispersion which is measured with the same units as the data. It is calculated as the positive square root of the variance and is therefore always a non-negative number.
The standard deviation of a sample, as opposed to a population, is denoted s.
