Final answer:
Accuracy and precision are two important concepts in science. To validate accuracy, compare your measurement to a known or accepted value. To validate precision, repeat your measurements multiple times and compare the results.
Step-by-step explanation:
Accuracy and precision are two important concepts in science. Accuracy refers to how close a measurement is to the true or accepted value. Precision refers to the consistency and reproducibility of measurements. To validate accuracy, you would compare your measurement to a known or accepted value. To validate precision, you would repeat your measurements multiple times and compare the results to see if they are close to each other.
