# Standard deviation definition

Standard deviation. (s) means a measure of the dispersion or variation in distribution, equal to the square root of the mean of the squares of the deviations from the mean root of the distribution, as set forth in Appendix E.
Standard deviation means an index of variability as set forth in Xxxxxx X. Xxxxxxx and Xxxxxxx X. Xxxx, Statistics, Probability, Inference and Decision, 164-5 (2d Ed. 1975). “Standing bid” means a pilot’s order of category preferences, as they exist in DBMS, for AEs, MDs, and VDs. A pilot’s category preferences may include:
Standard deviation means a measure of variability which is often used in the investment industry as an indicator of risk, and is calculated from the measurement of variance from the mean annual account return. A very high standard deviation indicates that the fund’s range of performance has been very wide, indicating a greater potential for volatility;

## Examples of Standard deviation in a sentence

• Where Fck = Characteristic compressive strength of 28 dayss = Standard deviation which depends on degree of quality controlThe degree of quality control for this work is “good” for which the standard deviation (s) obtained for different grades of concrete shall be as bellows: Grade of ConcreteFor “Good” quality of controlOf the six specimen of each set three shall be tested at seven days and remaining three at28 days.

• Standard deviation has been calculated using the trailing monthly total returns for the appropriate time period.

• S= Standard deviation The standard deviation for each grade of concrete shall be calculated separately.

• Sm = Standard deviation of the run means (the limits are shown on the chart).

• Standard deviation is the most widely used approximation of the risk of an individual investment or portfolio.
