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.

: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?
