Understanding Accuracy and Precision

What is the main difference between accuracy and precision?

• Both accuracy and precision are about closeness to the true value.

• Accuracy is about consistency, while precision is about closeness to the true value.

• Accuracy is about closeness to the true value, while precision is about consistency.

• Both accuracy and precision are about consistency.

In the dart example, what does it mean if the darts are close to each other but far from the bull's eye?

• Low accuracy, low precision
