We shall find median of the heights of the boys and girls separately.

Median of heights of boys:

N_xi = 37

⇒

Cumulative frequency = 19 falls in the height of 147 cm.

Thus, median height of boys is 147 cm.

Now, median of heights of girls:

N_yi = 29

⇒

Cumulative frequency = 15 falls in the height of 18.

Cumulative frequency, 18 falls in the height of 152 cm.
