Building Skills
Interpreting a Graph Doctors often record infants’ and young children’s weight and height on growth charts similar to the one for girls here. The meas- urements are presented in the form of percentiles. For example, a 30-month-old girl who weighs 28.7 pounds falls into the 50th percentile. This means that half of all 30-month-old girls weigh less than that child and half weigh more. Review the growth chart, then answer the questions that follow.
1. Into what percentiles does an 18-month-old girl fall who weighs about 28 pounds and is 34 inches tall?
2. Into what percentile would a 9-month-old girl fall who weighs 22 pounds?
3. How do growth charts illustrate that a child’s physical development is unique?
