 * Accuracy** is the degree of closeness of a measured or calculated quantity to its actual (true) value. Accuracy is closely related to **precision**, also called reproducibility or repeatability, the degree to which further measurements or calculations show the same or similar results.

accuracy is how close you can get to a certain thing.Precision is not so much how close you are to being accurate its being able to get the same result over and over again.EX) as in the game of darts accuracy would be being ableto hit the bullseye. Precision in the same game would be being able to hit any spot on the board more than once it wouldnt have to be the bullseye.

__Examples of Precision and Accuracy: __ · If you are playing soccer and you always hit the left goal post instead of scoring, then you are not accurate, but you are precise

· For example, an accuracy of ± 5% means that a value may lie between 95% and 105% of a given answer.  ** Sara C.
