Question

Precision refers to

how well a hypothesis matches the results

the level of refinement of a measurement or group of measurements

how close a set of data is to what it should be

how well an experiment's results match the results of other experiments

Answer 1

Precision in this experiment context is how close all your different measurements are to each other.
Accuracy would be how close your measurements are to a theoretical value.

Answer 2

So would it be the last one? @DanJS

Answer 3

I agree with @DanJS and here's one way to visualize the difference between `precision` and `accuracy`

Answer 4

Hmm so im thinking B.

Answer 5

I mean D.

Answer 6

C) `how close a set of data is to what it should be` is accuracy
