Disease Detectives B/C

we changed our minds we are doing a general cancer topic

What do you mean? You don't choose a topic unless maybe you're a proctor in which case you probably wouldn't be broadcasting what your test will be on.

we arnt in scince olypiad we get to choose what illness or plauge we get to do we have to do 3 science olympiad events in 18 weeks so thats why im brodcasting the info

I also appriciate all of you guys helping me and gsimmons with all of our questions even though all of this is a school project

Can you please keep that project discussion elsewhere? Not here, where it's a discussion only for the Disease Detective event in Science Olympiad!?!

Hey guys i need some helping with calculating relative risk and odds ratio.

On the nationals test from last year, it asks you to calculate the relative risk on a leggionaires disease thing:

But how would i use this formula (which i got from the disease detectives wiki):

(a/(a+b))/(c/(c+d))

in that table?

You can't, for that data table, because it isn't laid out in that format. You need to understand what relative risk is - the ratio of risk in your study group compared to some referent group. In this case, you use the lowest-risk group as the referent for the other three. It's not a very clear question, though - I feel like they should have given you a hint that you were doing an internal comparison of the four.

AHAHA Legionnaires' disease! It doesn't seem that the nationals tests are that much harder than the state ones, but unfortunately/fortunately for us, the state proctors have basically reused the same state test for the past 4 years.

what is the average amount of questions on a test (i need to know because we have to make a test for our class) based off of the real event from science olympiad

There is not really an average amount of questions. There can be 100 short questions or just 10 very long ones. It varies depending on the test.

For disese detectives i found out our minimum amount of questions

[EastStroudsburg13]

Minimum of what? It's helpful if you post more than the bare minimum of what you're trying to say because then nobody knows what you're asking for. And plus it takes up space on the thread.
