which of the following best represents accuracy but not precision?

2 Answer

  • Answer:

    D

    Explanation:

    Measurements that are close to a standard measured value is accurate. But when measured values are close to each other they are precise. For example, if one measures the weight of 1 kg of rice as 945 g and another person measure it as 955 g, then the second person’s ,measurement is more accurate. Now if the first person measured the same bag of rice thrice and got values 945 g, 946 g and 947g whereas the second person got values 955g, 950 g and 940 g, in such a case the first person’s measured value is more precise.

  • The answer is D.

    A models neither accuracy or precision

    B models precision and accuracy

    C models precision but not accuracy

    D models accuracy but not precision: this is because one of the darts is on the target which is accurate and the others aren't which isn't precision.
