Answer 1

You throw a dozen darts at a dartboard.

* If they mostly land all around the bullseye, you are **accurate**. Your results were all close to the target, even if they were spread out around it and not close to each other.

* If they mostly land off on the edge, but they’re all clumped together, then you were **precise**. You kept getting the same result over and over again, even if it wasn’t the target you were going for.

* If they all land near the bullseye *and* all clumped together, then you were accurate *and* precise.
