Disease Detectives B/C

[sciolyboy123]

Some basic things, go through a Div. C test and see all the calculations involved, then look it all up and add it to your resource sheet. The test will probably include bias and error but you don't need to know that for Div. B. Ignore z-score, and all other calculations similar to that.

Is an incidence rate = attack rate = incidence proportion?

Is an incidence rate = attack rate = incidence proportion?

incidence rate = incidence proportion = people sick/population/time period
attack rate = people sick/population

So no.

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.
