what is the difference between accuracy and precision and which is most important to scientific measurement?

Brief Explanations:

Accuracy refers to how close a measurement is to the true or accepted value. Precision is about how close repeated measurements are to each other. Both are important in scientific measurements. High - accuracy without precision can lead to inconsistent results, and high - precision without accuracy means results are consistent but wrong. In different scientific scenarios, the importance may vary. For example, in some medical tests, accuracy is crucial to get the right diagnosis; in experiments where reproducibility is key, precision is vital.

Answer:

Accuracy is closeness to true value, precision is closeness of repeated measurements. Both are important and their relative importance depends on the scientific context.
