Question

Why is accuracy is poor and precision is good

Answer 1

Answer:

Poor accuracy results from systematic errors. These are errors that become repeated in exactly the same manner each time the measurement is conducted. Accuracy is usually dependent on how you calibrate the system. For example, in the ocean depth measurement, the parameter directly measured is elapsed time

Precision is more important in calculations. When using a measured value in a calculation, you can only be as precise as your least precise measurement. ... Accuracy and precision are both important to good measurements in science.
