Answer:
Increasing precision with multiple measurements
Explanation:
The more measurements you take (provided there is no problem with the clock!), the better your estimate will be. Taking multiple measurements also allows you to better estimate the uncertainty in your measurements by checking how reproducible the measurements are.
Answer:
All measurements should be done twice to absolutely make sure that you have the correct measurement and to avoid any mistakes if you are like building lets say a table or doing a equation. The saying is measure twice cut once
