Experimental Design B/C

[packer-backer91]

What kind of statistics do you guys use for your "other relevant statistic"?

I always included: Range,mode,avg,(population) standard deviation. For the other relevant statistic it was dependent on what kind of experiment it was, when it was testing the effect of a different material has on an experiment I liked to include easy things like sum. I don't know if anyone else use sum ever but I did along with others like variance too just because it was so easy to calculate. sometimes also the slope of line of best fit, these were all statistics that i remember using one time or another.

Does anyone have any ideas about what we can do for an experiment related to friction? Our materials are just sandpaper, regular paper, several types of balls, cups, and a ruler.

[zyzzyva980]

Maybe make a ramp, using the cups as a support, and roll the balls down the regular paper and then the sandpaper? The only problem would be the lack of three measures of the IV. I did a similar experiment for my sixth grade science fair, rolling a car down a ramp with the textures of sandpaper, regular paper, wax paper, and wood.

So what happens when u get a bad experiment and have no way to measure statistics?

[zyzzyva980]

Do your best and try to find something to do that is quantifiable.

"Any student not addressing the assigned question or topic area will be ranked behind those who do, because not conducting an experiment is a violation of the spirit of the event." Does this mean that if the event supervisor somehow found out that the team didn't conduct their experiment (due to highly inaccurate data or something else), they will be ranked behind those who did?

Yes. If, during the course of the event, the supervisor notices that you're not doing the experiment and marks you down somewhere for that, you can be 2nd tiered.

Do the experiment, and make sure it's quantifiable.

Could anybody that has already had their state tell me what kind of experiment they had? Was it a chemistry or was it a physics experiment?
Any Tips would help!!!!

We had to do conservation of energy, using a random set of materials- the easiest experiment was a pendulum.

We had ours last weekend in Illinois, and there were several topics we could've used such as gravity, resistance, kinetic energy, etc. It was a physics experiment. The materials given were a cup, rubber band, rubber ball, wiffle ball, cardboard piece (6 in x 1 foot), sand paper, aluminum foil, construction paper, string, tape, scissors, and a toy car.

I would suggest just doing what the Wiki Site says: KISS. Keep it simple, stupid. We got a gold using this method.
