Suppose that I visualized a distirbution and noticed that it was multimodal. For example, I collected the heights of a bunch of students.

enter image description here

I notice that the distirbution is multimodal. How would I investigate the cause of this multimodality?

    $\begingroup$ I'm surprised that so many students have negative height! $\endgroup$ – Sycorax Mar 26 '16 at 16:53

    $\begingroup$ Among many other possibilities, how about half the students are in 6th grade and half in 10th grade? $\endgroup$ – Mark L. Stone Mar 26 '16 at 17:04
  • $\begingroup$ You are right Mark. I'd just love to hear some advice on how to approach this. $\endgroup$ – user46925 Mar 26 '16 at 17:08
  • $\begingroup$ I would initially think it would be due to gender. But it could be due to students by grade. My approach would be to graph a stacked histogram. $\endgroup$ – user46925 Mar 26 '16 at 17:08
