I do believe that they're supposed to give you a copy of the rules.

Hey, me and a couple of other people just signed up in our school for experimental design and we have almost no time to prepare. We have a team of pretty smart people and we're definitely capable, but I wanted to know from any of the experts on here how you would go about practicing. We know the rules in and out but we still want to get in some hardcore practice in the weeks to come, I hope someone can help with a way to practice this event. Anyone?

Try doing some practice experiments. Have a coach or a teammate grade you based on the rubric. A list of experiments can be found in the wiki.

I agree, just do an experiment once a week and you should be good, also keep it simple experiments with alot of factors are a no bueno, like at regionals a few years back we got a mini catapult, rubber balls, rubber bands, tape, and a meter stick. The obvious choice was a catapult but we decided to do a drop and bounce experiment, (If the color of the ball changes the structure of the balls, then the balls should bounce different heights). It was a good decision, everyone else in our block used the catapult, people were running everywhere for balls that got thrown to hard, catapults were slipping, it was not good. We ended up getting third which i think is decent, so in short practice, and keep it simple. :D hope this helps
SO stressed!

Yeah, I definitely like that idea of thinking outside the box and doing a different experiment than would be expected, does anyone have a link to the experimental design wiki? I googled it but couldn't find anything. Also, any other advice is welcome still.

Here's the wiki http://scioly.org/wiki/Experimental_Design theres a whole directory on the front page under the event forums, and above the general chat ones. Oh theres also some practice trials on the bottom of the wiki they aren't the best in the world but they will help.

Yeah. I'm not on this event (but I had a schedule conflict with my beloved Dynamic Planet, so I have to switch, hopefully to this one), but I've heard that they're not looking for someone to cure cancer or make a nucleur reactor out of post-it notes, marbles, and a ruler. They want really basic stuff. Which is good for us anyway, considering the time restriction.

Yeah, you'll need to maximize the use of your time. Having three people is extremely helpful.

i know how the to do the measure of central tendency, variation, and regression analysis, but the "other appropriate statistic used" i'm stumped on, i need just a few suggestions to get going.

hold up...what's central tendency? and by variation, do you just mean range and standard deviation?

I would actually agree with your coach on this one. You may or may not have the rules near you when performing this event. Fortunately, the format of the final result should never really change. Know what you need to include, and be sure to be very clear - if a judge can't find a part of your lab, you will not get the points. And as we all know, we like points in Experimental.
