Four friends measure the length of a 6-millimeter-long grain of rice. They record their measurements as shown.Andrey:7 mm, 5 mm, 6 mm, 8 mmMariya:7.41 mm, 8.54 mm, 5.12 mm, 6.23 mmYuto:6.1 mm, 5.9 mm, 6.3 mm, 7.2 mmMisaki:5.843 mm, 6.981 mm, 5.334 mm, 7.632 mm

Compare each measurement with the actual length of 6 mm. Yuto’s measurements differ by 0.1, 0.1, 0.3, and 1.2 mm, for an average difference of 0.425 mm. This is smaller than the average difference for the other friends, so Yuto’s measurements are the most accurate overall.
