Question

Precision is a measure of how close an answer is to the actual or expected

value.
True or false ?

Answer 1

i’m pretty sure it’s true

Answer 2

False

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 detected.........eventually, invariably after you have shot your mouth off to your professor.
