An averaging of data in space or time, designed to compensate for random errors or fluctuations of a scale smaller than that presumed significant to the problem at hand.

Thus, for example, a thermometer smooths the temperature reading on the scale of its time constant; the analysis of a sea level weather map smooths the pressure field on a space scale more or less systematically determined by the analyst by taking each pressure as representative not of a point but of an area about the point.
See consecutive mean, curve fitting, filtering, bloxam.

  1. Regular markings on an instrument used to allow the reading of the measured quantity or setting.
