In the sciences, it's important to distinguish between the accuracy and precision of measurements. Accuracy refers to how close measured values are to a true value. Precision refers to how close measured values are to each other. A common metaphor used to illustrate the difference between these terms is a bull's-eye, or target. Darts thrown accurately at a bull's-eye all hit close to the center of the target but not necessarily close to each other. Darts thrown precisely at a bull's-eye, by contrast, all hit the same spot but not necessarily at the center of the bull's-eye.
Which term matches the picture?
A. accuracy
B. precision
