We used an online growth chart to find percentiles for the height and weight of a 16-year-old girl who is 66 inches tall and weighs 118 pounds. According to the chart, this girl is at the 48th percentile for weight and the 78th percentile for height. Explain what these values mean in plain English.

The girl's height is more than the 78 percent of the 16 year old girl

and,

the girl's weight is more than the 48% of the 16 years old girl

Explanation:

Given:

the height = 66 inches

weight of the girl = 118 pounds

the girl's percentile of weight = 48

the girl's percentile of height = 78

The percentile is the value below which percentage of the other observations are observed.

this means,

that the girl's height is more than the 78 percent of the 16 year old girl

and,

the girl's weight is more than the 48% of the 16 years old girl
