Precision and accuracy

So many people don't understand that these are fundamentally different aspects.

-Precision is basically how many significant digits, or how many digits right of the radix point.
-Accuracy is how close the measurement is to a target value.

For example:

Dale's discus throw was measured PRECISELY at 36.821 meters.
Bob's discus throw was measured at around 50 meters, plus or minus 2 meters.

Since the target was 50 meters Bob's throw was more ACCURATE than Dales.
