Sorry for double posting, but I have a question. When it comes to division C Disease Detectives, I know statistics are required. Is it an understanding of the statistics that is usually required, or is it being able to actually apply them to problems, and solve? Thanks!

I'd definitely say both. I've seen questions that ask you to find standard deviation, IQR, 95% confidence intervals, z scores, etc, but I've also seen questions that ask if something is a Type I or Type II error and/or ask for interpretations of confidence intervals and p values. On the Cy-Falls test for this season, there was a really good question using the Cochran-Mantel-Haenszel test that I found unique and interesting.

Adding to that, I feel like for some of the more involved statistical tests (eg. t-score, chi-squared), we just have to know their applications as opposed to calculating such values. Although, you should know calculations for CMH, age adjustment, and the like. These values are a bit more straightforward to calculate, and they're more directly related to epidemiology.

So much to do, so little time.
