If we wanted to explore the idea that mother's smoking might explain the variation in birth weight, what visualization might be helpful to us?

If a mother is smoking and there are significant birth weights, a bar graph will be most effective. A bar graph can show how many children have similar weights, and you can tell which weights are most common.

Hope this helped.
