i shall go back to my meditation.... OMMMMMMMMMMMMMMMMM

Thanks for the links! I liked the last two. They were fun hehe
Does anyone know of any good sites that have a lot of calculation problems? i.e. odds ratio, relative risk, etc.

boom werido shot anyway im all done with riginols >.<

:O OMG MINE WAS AT GRAND VALLEY TOO!!!
What did you place? I got 8th. I would have placed higher if my partner had put stuff on the note sheet I had been telling him too (having 6 events and 5 notesheets is hard to manage, so I put Disease Detectives on him)

Anyway, what is the difference between Risk and Risk Ratio? My partner and I were really confused by that.

Hey has anyone else seen standard deviation on their tests? We've seen it three times at invitationals but oddly enough at regionals it wasn't on the test... thoughts?

Standard Deviations are a logical thing to be on there, but I havent seen any. Can you explain how to use them?

Standard deviation in simple terms is the average something is away from the middle. On a test if you were given a chart they may ask you to find the average, the mean, the median, and then the standard deviation. Many calculators actually have the formula on the inside cover and if yours doesn't then you can add the formula to your cheat sheet. The first time I had it on a test I wasn't in a math class and so I was horribly lost but once you learn how to use the formula (just by practicing with a few practice problems) it's actually rather simple. Good luck!

Hmm... does anyone know exactly how much vocab is needed on the tests? I'm got a few 20 page glossaries, but are they really necessary? I've been told that aside from basic terms, you can use the other ones to "impress" your judges... is there any other use aside from that?

[Chikuwa]

In my experience (in C-Division, at least), sometimes tests ask you straight out "what does pandemic/epidemic/outbreak/etc." mean. also, one of the state tie breakers for ny c-division was just around 20 or so definitions with a blank next to them, and you had to identify the term that it described (no word boxes or anything).
In any case, your main focus should be learning all the 'methods' you'll need for the test. it'll help to know the vocab, however, to understand what the test may be asking of you or to answer those questions where they ask you to define things. (if you want to know which vocab specifically, it may help to take some past tests and see what kind of vocab they use.)

Well, since someone here asked for standard deviation I found this site and I like it.

The concept in here is pretty good. I hope it helps

wasnt i talking to you in the dyimic planet thread? werid but hi and i have no idea me and my bud guessed

[hanajitenshi]

i think states are today for people

Risk ratio = relative risk (a/(a+b))/(c/(c+d)) on a two-by-two table. It takes into account exposures. Risk (absolute risk) is just the overall chances of getting the disease.
