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.
Cross-sectional is the cheapest and fastest one, and it also presents the greatest likelihood of inaccurate information.

Ok, that's what I thought. Case studies seem to really be our downfall; it's just that there are so many different opinions on them. Anything else really important I'll need to know study-wise?

Don't know if anyone else already mentioned these, but know the formulas associated with each design (ex. odds ratio, relative risk) and also the pros and cons of each. A list can be found on the soinc.org website.

Where exactly is the list? I am assuming it is on this page: http://soinc.org/disease_detectives_b

The formulas and equations can be found on the 2012 training handout. The 2012 Training powerpoint also has more info on the case studies.

Sorry, I can't find the pros and cons of case studies, but I'll keep looking.

The Virginia Science Olympiad Division B On Febuary 28, 2009's anwser key has the pros and cons of case control, cohort, cross-sectional, and expirimental or trial studies. I found it to be pretty useful

Yeah, but in this case it is wrong. Case-control studies are clearly faster and cheaper than cross-sectional studies, because all you need is a group of cases and a group of appropriate controls. For a cross-sectional study, as the name implies, you have to attempt to get a cross-section of a population. That is why you can get prevalence data from a cross-sectional study, but not from a case-control study.

Who liked the format this year? I thought it was a little weird and a bit to easy. Honestly we thought we failed when we left the room. They cut down the lengthiness :x . We ended 3rd though :D (division b)
