Examples of accurate but imprecise measurements

1 answer:

8 0

Accuracy is how close a value is to its true value. An example is how close an arrow gets to the bull's-eye center. Precision is how repeatable a measurement is. An example is how close a second arrow is to the first one (regardless of whether either is near the mark).
