Answers:
Correct Answer: (ii) Results of student A are both precise and accurate
Explanation: The A and B students have average reading which is close to correct reading that is 3g. The recordings of student A are very accurate as they differ by ± 0.01, while readings recorded by student B differ by ± 0.05. Hence, student A results are more precise and accurate. Accuracy means the closeness of the various dimensions by the same quantity and accuracy is a testament to the particular value rather than the true value of the results. Student A results are very close to 3g.
