group of measurements. Resolution is a measure of the fineness of a
measurement. Together, the three define how well a data-acquisition system
performs. To understand how the three relate to each other, consider "target
practice" as an analogy. Figure Accuracy, Precision, and Resolution

four targets. The bull's eye on each target represents the absolute correct
measurement. Each shot represents an attempt to make the measurement. The
diameter of the projectile represents resolution. The objective of a data-
acquisition system should be high accuracy, high precision, and to produce data
with resolution as high as appropriate for a given application.
