Question

The measure of how closely a set of measurements are to each other is the best definition for which of the following terms. a error b uncertainty c accuracy d precision

Answer 1

D. precision. At first glance you can mark out A and B because the answers does not relate to the question. If question had said "what do you call it when the measurement is close to the actual answer" then you would have picked C. So that leaves you D. precision.
