What's the difference between accuracy and precision?

Title:
What's the difference between accuracy and precision?
Speaker:
Matt Anticole
Description:

When we measure things, most people are only worried about how accurate, or how close to the actual value, they are. Looking at the process of measurement more carefully, you will see that there is another important consideration: precision. Matt Anticole explains what exactly precision is and how can help us to measure things better. [Directed by Anton Bogaty, narrated by Addison Anderson].
