The question will almost always (ideally, should) tell you what to express prevalence and incidence in terms of, whether it is as a percentage, per 100,000, or per 1,000. (i.e. They can be expressed in any of these ways, just make sure you answer the question posed.)

Is there a website that has good info on how to identify study designs from case scenarios?

Science Olympiad's own website (soinc.org) has a bunch of great resources under the disease detectives page. there are documents and info on case designs and practice tests.

Like, if a restaurant at an airport was only open on alternating days, or something? So it would always come from the same place, but at alternating times.

I have a practise test in front of me, but no answer key. So what is considered to be the "most rigorous study design"? Isn't it experimental?

according to nichd.nih.gov, "randomized control trial" would be the most rigorous. So yes, I think that is similar to experimental.

RCT is a type of experimental.

Is cross-sectional the cheap/fastest one, or is that case control? I've seen it from both sources both fairly reputable), just wanted another opinion.
