I'm new to this event and did research on everything mentioned in 2019's rules, which included Hill's criteria for causality; thus, is it necessary to research the postulates? Also, this question has definitely been asked already, but to what extent do participants in Division C need to understand statistical analysis? Thank you!

It wouldn't hurt to know Koch's postulates, as it may come up as it comes as part of the history of epidemiology, but I haven't seen it on a Div C test as of yet.

The wiki is a good place as it lists what advanced statistics are important, but doesn't really explain how to use those. I'm pretty sure the advanced statistics are covered in the WHO textbook, and are likely also covered in the CDC textbook. Tests can basically give you a set of data and ask you to apply a statistical analysis measure to it, so knowing the advanced stats is pretty helpful.
