Maybe by #sigma_d#, #"the standard deviation..."#

Explanation:

As you should know, #"accuracy"# refers to the closeness of a measurement to the TRUE value; whereas #"precision"# refers to the repeatability of a measurement. Precise measurements may be inaccurate due to some systematic error, and accurate measurements may be imprecise given the scatter, i.e. the range of a series of measurements.

You will introduced to a range of ways of dealing with error in your analytical chemistry text. This will also include formal definitions of #sigma_d#...
