Yup, don't ignore what's in the rules. Our DD/C Div team made it a point to practice the stats quite well. Admittedly they were not the most wonderful writers but they nailed the stats at state and got the gold. I know that that gold is not from writing eloquently (or even neatly...), so I suspect it's because they quickly could do the chi-squared problem. A few days after state, I was talking with another local coach whose C/DD team got a middle sort of score and this coach said that their DD pair was complaining that the test counted the chi squared problem too highly. So, they might've been surprised by the problem at state.
Just because this year it didn't have Fisher's exact, chi squared, paired t test or whatever doesn't mean that next year it won't.
If you've got a pair on DD where one kid is a junior or senior and the other is a freshman, perhaps task the older kid to be the stats expert...
