test metrology

What is the main objective of metrology?

• To standardize units of measurement

• To create new measuring devices

• To study the accuracy and precision of measurements

• To eliminate all measurement error

What is a gross error in measurement?

• A systematic error that is significant

• A minor error that can be ignored

• An error due to environmental factors

• A random error significantly higher than expected
