Answer:
When taking scientific measurements, it is important to be both accurate and precise.
Accuracy represents how close a measurement comes to its true value. This is important because bad equipment, poor data processing or human error can lead to inaccurate results that are not very close to the truth.
Precision is how close a series of measurements of the same thing are to each other. Measurements that are imprecise do not properly identify random errors and can yield a widespread result.
