Accuracy - refers to the correctness of a measurement
Precision - refers to the reproducability of a measurement (do something over and over again)
Bullseye Example:
Accuracy is hitting the bullseye
Precision is hitting a certain point of the target over and over again
In science, and many other fields, the goal is to be accurate and precise. You want to hit the bullseye over and over again. You want to make that field goal every time you kick that extra point. You want to make that basket every time you line up at the foul line.
This is a topic that my physical science students really struggle with this is an excellent way to explain it! Do you mind if I use your bulleye's image to show my classes?
