Question

Three wires of actual length 13.9 cm were given to three students to measure its length using

their own device. They recorded the length as 13.82 cm, 13.904 cm and 13.1cm. Which among

these observations are (i) Precise (ii) Accurate​

Answer 1

The recorded length 13.904 is more precise than the other two readings as it is more accurate and more near to 13.9

We can also assure the correctness of our answer by subtracting all the three readings from 13.9, where the difference between the reading is less than the reading must be more precise
