Which of the following best represents both accuracy and precision

Measurement B

Explanation:

Precision refers to the closeness of two or more measurements to each other.

For Example: If we measure a length three times and we get 3.5 m each time. Then the measurement is very precise.

Accuracy refers to the closeness of a measured value to a standard or known value.

For Example: If the length of the substance is 4 m and one person measures 3.9 m and another person measures 3.8 m. Then, the length measured by first person is more accurate.

Thus measurement B represents both accuracy as well as precision as the darts are close and pointed at the center.

the answer is 0.8m.
