All the point values are doubled this year, this could be a good or bad thing.

It's probably so they can be a little more precise with their scoring, so they don't have to, say, take off a whole point from a 2 pointer when there was really just a minor error.

Yeah; I think this is better. :)
But other than that... I've just moved from Div. B to C - what should I know that's really important in the shift?

It's essentially the same event in both divisions, which is nice. In most events they add stuff to Division C to make it tougher- that doesn't really happen in Experimental Design. There's going to be some more statistics for you to learn how to do... and that's about it. What makes Experimental more difficult in Division C is that everyone should have a little bit more experience and everyone should know what they're doing, so the competition is a little bit tougher.

Ah, I see. Well, that's good. I think. I'll train with my partners so we can do well!

Does anyone know if there is any way to see the winning experimental from last year for C div? I'm wondering when they stopped (if they did) including the winning team's experiment in the Tests CD/book that they publish after nationals. As far as I can tell 2008 was the last year they included this, but if anyone knows otherwise, please let me know!

Also what do people make of the fact that any kind calculator can be used (c div)?

Ha, I'm not sure what to make of that yet. Statistics are going to be helluva lot easier, and so are a lot of other things. Once we start practicing, we'll see how it all adds up.

This is the best news that I have ever heard! :D Makes life so much easier... I'm sure many will still require work to be shown though.

I didn't know that we had to show work for things like statistics. Each section of the rubric for statistics is worth one point each. Would they give no credit for a correct measure of central tendency without any work shown? And this is a serious question - I myself have no idea what the judges would do.

For our hypothesis, are we allowed to predict no relationship between our IV & DV's?

Yes... but if you're doing that your experiment is probably not a good one.

Well...

I don't know if "no relationship" is the best phrase to use

I simply meant that the DV won't change for the various levels of the IV
