The standard deviation is related to the spread or distribution of control results about the expected mean. Whereas the mean is an indicator of central tendency and therefore related to accuracy or systematic error, the standard deviation is a measure of the width of the distribution and is related to imprecision or random error.

The acronym scada, by containing the word “control,” implies two-way communication (measurement and control) between the master location and the remote location. In applications where the flow of information is strictly one-way (simplex) from the remote location to the master location, “telemetry” is a more apt description.
