53 92 110 133 150 165 |
Solution
The graph represents the relation between the age and height of both boys and girls.
From the graph we can conclude that :
During puberty, there is a sudden increase in height of both boys and girls. It can be observed that during the age of 4-8 years, girls have less height as compared to boys. However, as soon as girls reach 12- 13 years, their height shows a sudden increase and becomes more than boys. In later years, growth in both sexes becomes stable.
