Yannick’s class measured the width of one leaf several times. The values that the class recorded included 10 mm, 8 mm, 15 mm, 5 mm, and 13 mm. What is lacking from the measurements that the class made?

The measurements range from 5 mm to 15 mm, so they are not close to one another. That means the measurements lack precision; precision is about how consistent repeated measurements are. Repetition was included because the class measured the leaf several times.
