The source of all knowledge

Of course man

Thanks. I was confused because Page 3-11 in the cdc principles of epidemiology book says attack rate is a synonym for incidence proportion, so just wondered if that is the prevailing view since it also sounds like (on p. 3-10) different people use these terms differently.

Welcome. If there is anything else that you need help understanding, you have many helpful people in this forum. Btw that CDC book is really good for studying and researching basics of epidemiology. I advise you to keep reading it because it strengthens your skills in being a disease detective.

I will be competing in this event at Nationals for the first time this year. Will someone explain how it works at Nationals? With all 60 teams going at once, do they split into rooms or is it all one big auditorium type set-up?
Also, how should I prepare for the test? How have previous tests been laid out?

The General Rules page of the rules has a schedule that splits the 60 teams into 3 different hours for Division C, and I don't think it's much different for Division B. The tournament website has a PDF with a photo of the Disease Detectives event room.

Isn't it a single time block for B?

Yes, it's the very first time slot (7 AM to 8AM).

The DD event at Nationals is usually held in two rooms - one for Div B and one for Div C. These are generally big lecture halls. Team members sit next to each other and are separated from other teams by one or more seats. According to the schedule on the tournament website - all teams will compete at the same time 7-8am. That gives us time to score them. wrto stats - things like odds ratios, incidence rates, relative risk - are not really stats and are part of both Div B and C events. There is a list of stats - chi square, fishers exact... things that involve p-values or stratified analysis - that are part of Div C - not B. One of the events from 2013 should be up on the CDC website - check it out. We generally use the same scenarios for Div B and C but many of the questions are different. We try to set it up so understanding is more important than memorizing. These events are long and brutal, most teams will not finish them all - do your best.

Is it going to be like the Nationals test from when Population Growth was last the topic?

Probably. I would assume so, but disease is disease and you probably will never know everything on the test.
