Also, make sure you make your experiment simple, so that your report can be detailed.

Or you could be doing the experiment and have someone else write at the same time. That's what our team did, there are many strategies.

Yes, it depends on how many are in your group and what your talents are. For instance, the guy in my group who can't even spell "trial" is obviously not doing the write-up, while I found out that I'm not very good at doing the experiment. It varies with every group.
Advice on the overall event: Be creative, but always be specific.

We usually split our group and have each member do one third of the write-up, with the person doing the graphs completing the experiment. The important part is to choose a simple experiment that you already know the outcome of (so the person doing analyses can start early) and to focus on the wording of the report.

Not quite. You do have to make an experiment out of the random things, but then you still have to make a write-up, conclusion, hypothesis, etc. like the regular scientific method. They don't really tell you anything, so you are 'on your own' for this event. It is not nitpicky and precise so you can literally do anything without blowing something up or something like that.

An example of supplies would be:
Items:
Tennis Ball
Golf Ball
Ping Pong Ball
Bouncyball
Meter Sitck
Pencil
Paper
Surfaces:
Tile
Carpet
Hardwood flooring
The experiment you could do is measure how high the balls will bounce on the three different surfaces using the centimeter side of the meter stick. When you have found data record it on the piece of paper, using the pencil. Also as you do the experiment go through the scientific method.
As germinator said:

For clarification, what does it mean to "operationally define" a variable?

I think that means how something is measured or classified. Like, how far a ball rolls, measured using a ruler in cm. Or, the ages of a group of people, split into groups of 0-5, 6-10, 11-15, etc years old.

Can somebody please explain what the statistics are for C division? I need help with the measure of variation and regression analysis.
I know this is more relevant for specific experiments, but in general what "other appropriate statistics" would you recommend?
