![6. Measures of relative standing (percentiles and quartiles), interquartile range
A growth chart is a plot of the percentiles of growth measurements, such as weight and height, for a population of infants or children. It is used by
pediatricians to assess a child's growth over time.
The Centers for Disease Control and Prevention (CDC) is a U.S. agency devoted to the protection and promotion of public health. Through one of its
units, the National Center for Health Statistics (NCHS), the CDC has developed growth charts for clinical use by health professionals. The most recent
charts were published in 2000.
The 2000 CDC growth charts were developed using a reference population of infants. A pediatrician looks up one of the charts and finds that the 10th
percentile for weights of baby girls at 7-1/2 months is 16.5 pounds. This means that
of the 7-1/2-month-old baby girls in the
reference population weigh 16.5 pounds or less, and
of these baby girls weigh 16.5 pounds or more.
The 2000 CDC growth charts use a reference population of both breast-fed and formula-fed infants. It has been observed that breast-fed babies tend
to gain weight more rapidly than formula-fed babies in the first 2 to 3 months of their lives, but they tend to weigh less than formula-fed babies from
6 to 12 months.
Sarah is a healthy baby who was exclusively breast-fed for her first 12 months. Which of the following is most likely a description of her weights (at 3,
6, 9, and 12 months of age) as percentiles of the CDC growth chart reference population?
O 10th percentile at 3 months; 40th percentile at 6 months; 75th percentile at 9 months; 95th percentile at 12 months
O 75th percentile at 3 months; 85th percentile at 6 months; 95th percentile at 9 months; 95th percentile at 12 months

O 30th percentile at 3 months; 30th percentile at 6 months; 30th percentile at 9 months; 30th percentile at 12 months
