1. What is the difference between precision and accuracy?
Overview
Manufacturing engineers must understand the difference between precision and accuracy. Precision refers to how close a measurement is to another measurement, while accuracy refers to how close a measurement is to the actual value. Candidates should be able to explain the difference and give an example of each.

Knowledge of precision and accuracy
Ability to communicate technical details,
Sample Answer
Precision is how close a measurement is to another measurement. Accuracy is how close a measurement is to the actual value. For example, if I measure the length of a table at 10 feet, then measure it again and get 10 feet, I have high precision but low accuracy. If I measure the length of a table at 10 feet and get 10 feet, I have high accuracy but low precision.
