Precision is a measure of how close an answer is to the actual or expected value.
True or false ?

False

Step-by-step explanation:

Precision  describes repeatability.  

Accuracy  describes the closeness of a measurement to the actual value.

 So your measurements may be precise but not accurate; for example if you used a faulty measurement system. And of course, you could get accurate results SOME of the time (which describes the exprerience of most researchers).

Errors in precision are usually detectedeventually, invariably after you have shot your mouth off to your professor.
