Q.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?

Answer :

The graph shows the relation between the age and height of boys and girls with a comparison between both of them.

From the above graph, we conclude that initially boys grow faster than girls from 0-8 years.

At reaching puberty, both has a sudden rise in their height, though the girls grow faster than boys from 8-16 years.

Both reach their maximum height at the age of 20. Here the boys show a greater increase in height than girls.

Now, growth in both of them comes to a halt, upon reaching the end of adolescence as the hormonal changes and their secretions had become stable at this point.
