Standard Deviation Value

A Standard Deviation Value is a dispersion statistic value produced by a standard deviation measure relative to a mean value.

• Context:
  • It can range from being a Population Standard Deviation Value (for a population mean) to being a Standard Deviation Estimate (from a sample mean).
  • It is in the same Metric Space as the Input.
  • …
• Counter-Example(s):
  • an Average Absolute Deviation Value from an Average Absolute Deviation Measure.
  • an Expected Deviation Value from an Expected Deviation Measure.
• See: Estimated Value.

  • In statistics, the standard deviation (SD) (represented by the Greek letter sigma, σ) is a measure that is used to quantify the amount of variation or dispersion of a set of data values. A standard deviation close to 0 indicates that the data points tend to be very close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the data points are spread out over a wider range of values.
