1. Case control? 2. He is considered the father of field epidemiology and the first person to use a spot map in an epidemiological study.

For part 1, Wikipedia has a different answer, but if someone could find a concrete source that would be good.
2 is correct!

I just assumed case control because I assumed he was comparing people with an without disease to find a common exposure (in this case, a water pump).

Wikipedia said it’s the first ecological study, but I don’t really understand ecological studies myself and no website has given a good view of the difference between ecological and case control because they’re really similar sometimes (ie in this case).

I think that ecological studies are case control studies for a larger population defined using geographical data. In the case of the cholera outbreak, John Snow used a spot map to figure out the common source. I feel like ecological studies are a broader term with case control studies being subset of it.

That sounds about right, so Froggie was correct!
