Also asked, what is precision measurement?
Precision refers to the closeness of two or moremeasurements to each other. Using the example above, if youweigh a given substance five times, and get 3.2 kg each time, thenyour measurement is very precise. Precision isindependent of accuracy. You can be very precise butinaccurate, as described above.
Also, what is the difference between precision and accuracy? Precision and accuracy are often usedinterchangeably, but in science they have very different meanings.Measurements that are close to the known value are said to beaccurate, whereas measurements that are close to each otherare said to be precise.
what is an example of precision?
Accuracy is how close a value is to its true value. Anexample is how close an arrow gets to the bull's-eye center.Precision is how repeatable a measurement is. Anexample is how close a second arrow is to the first one(regardless of whether either is near the mark).
Why is precise measurement important?
When taking scientific measurements, it isimportant to be both accurate and precise. Accuracyrepresents how close a measurement comes to its true value.This is important because bad equipment, poor dataprocessing or human error can lead to inaccurate results that arenot very close to the truth.
