Question Question 10
The table below shows the data on likely heights of boys and girls as they grow in age. Draw graphs showing height and age for both boys and girls on the same graph paper. What conclusions can be drawn from these graphs?
The following conclusions can be drawn from these graphs:
- From 0 to 8 years, height of boys increases more than girls so boys are generally a little taller than girls in this age group.
- Both boys and girls experience a sudden increase in height during puberty.
- At the onset of puberty when the adolescence period starts (around 12 years), height of girls show a sudden increase and they become taller than boys.
- Around the age of 16, height of boys catches up with girls and both are equally tall.
- Afterwards, the height increases and becomes stable around 20 years of age with height of boys being a little more than girls.
