what is accuracy and precision and also give examples?
Answers
Answer:
Accuracy refers to the closeness of a measured value to a standard or known value. Precision refers to the closeness of two or more measurements to each other. ... Using the example above, if you weigh a given substance five times, and get 3.2 kg each time, then your measurement is very precise.
example: 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).

Explanation:
accuracy is closeness of the measurements to a specific value, while precision is the closeness of the measurements to each other.
The closeness of two or more measurements to each other is known as the precision of a substance. If you weigh a given substance five times and get 3.2 kg each time, then your measurement is very precise but not necessarily accurate. Precision is independent of accuracy.
