The median $Q_2$ is the point such that the area under the bars each side of $Q_2$ is equal.

The lower quartile $Q_1$ is the point such that the area up to $Q_1$ is one quarter of the total area.

The upper quartile $Q_3$ is the point such that the area up to $Q_3$ is three quarters of the total area.
