That's right.
So you're suggesting that it technically does include the time period?

Technically, but not in the calculation.

Technically, but not in the calculation.
Well, same example but over two years:

Example: 40 people are infected with tuberculosis, with 100 people being at risk to contract disease in 2013 & 2014.

The incidence rate is 40% over 2 years.
The incidence rate is 20% per year.

40/100/2 = 20%

Yes. In that case, it would be right.

Hello there! I am trying to get a head start over the summer on Disease Detectives Division C. Anybody know about how much of the test is composed of statistical analysis like Chi Tests etc. ? I know the official guide sheet says less than 10%, but sometimes the test makers do it differently.

You kind of answered your question—it depends on the test maker. In tests I've taken, I haven't seen it a lot, probably less than 10% as you said.

Anybody know if the Disease Detectives CD on soinc.org is useful or not? I want to practice some more tests besides the ones on scioly.org.

I know that for Div. B, it was pretty helpful. Not sure about Div. C.

In Disease Detectives this year, I noticed that the test I took at Nats was significantly different from the one I took at any other competition (invites, state, regionals). It required much more critical thinking and problem solving skills than just memorization of vocab words and RR/OR formulas.

Just out of curiosity, have any of you guys who took the test at Nats noticed the same thing? It almost seemed like the test was written for an entirely different event at Nationals than at any other tournament. (though I did feel that the Nats test was very well-written and challenging)
