Question

Unit test in science if you took it. It's question 10 four students measure the length of a paperclip whose actual length is 3.2 cm. Whose measurement is precise but not accurate? IS IT A OR B I DONT KNOW A.Samuel: 2.7, 2.7, 2.7, 2.8 B. Jose: 2.2, 2.6, 3.0, 3.3 C. Nikita: 3.1, 3.1, 3.2, 3.2 D. Anne: 2.6, 3.2, 3.2, 3.6

Answer 1

Answer: A.Samuel: 2.7, 2.7, 2.7, 2.8

Explanation:

Given that actual length = 3.2cm

Samuel's score is precise but inaccurate. This is because, each of Samuel's four measurements are close to each other even though it lacks accuracy, because it is a bit far from the actual value of the measurement. Hence, of the measurements given for each of Samuel, Nikita, Jose and Anne, Samuel's score exhibits precision but inaccurate. Nikita's score is both precise and accurate
