1. Measures of location - Percentiles, deciles, and quartiles
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 that has developed growth charts for clinical use by health professionals. The
most recent charts were published in 2000.

Age (months)
The 2000 CDC growth charts use a reference population of both breast-fed and formula-fed infants. 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.
