If your interviewer asks (tests) you about how to conduct a study of a particular disorder/disease in a specific population, how should you answer?

What are the keys points to address?

Follow the scientific method.

1) Make an observation in the population.
2) Come up with an explanation (i.e. hypothesis), as well as alternative explanations (i.e. alternative hypotheses).
3) Develop an approach to test the hypotheses; also known as research design (include positive and negative controls).
4) Gather data/observations using the approach, and see if they are in line with your expectations (i.e. hypotheses).
5) Because your data will rarely fit within the confines of a hypothesis, there is always unexpected findings (if you don't see them, you aren't looking hard enough), proceed to Step 2 again. Repeat as needed.
