Verified answer

My teacher used a dartboard analogy.

Precise and accurate = Three darts directly on bullseye.

Accurate not precise = Three darts surrounding the bullseye, but none of the darts are very close to each other

Precise but not accurate = A group of three darts that is not close to the bullseye at all.

Neither precise nor accurate = three dates spread randomly around the dartboard.

Or, alternately:

Precise and accurate = A scale measures a 1kg block as 1 kg every time

Accurate not precise = A scale measures a 1 kg block as .97 kg, 1.3 kg, and 1 kg.

Precise not accurate = A scale measures a 1 kg block as .98 kg every time

Neither precise nor accurate = A scale measures a 1 kg block as .34 kg, 2.5 kg, and 10 kg.
