Question

Distinguishing accuracy and precision Four research teams measured the speed at which signals travel down a certain type of nerve fiber, and what each team wrote in its team notebook is shown in the table below. Suppose a later and more reliable measurement gives 31.0 m's for the signal speed in the same type of nerve fiber. Decide which of the earlier measurements was the most accurate, and which was the most precise. team what was written in the notebook most accurate most precise measurement measurement X 5 ? "between 28.6m/s and 29.4m/s *35.m/s 16.0% "33.0m/s 0.2m/s" "31.4m/s

Answer 1

Accuracy is how close the value measured comes to actual value. This is option d 31.4 m/s

Precision is how mucgh measured values agree with each other. This is again option D, 31.4 m/s as there is only one measured value, no contradictions
