The entire "Division B" section has been removed, and "line of best fit" replaced with "other appropriate statistic used". I used to give mean, median, mode, range, standard deviation, regression analysis, and then another statistic, but now it just says "mean, median, mode, range, or other appropriate statistic used". Does that mean we just need to pick one of them to do? Or perhaps just one statistic each for measure of central tendency and measure of variation? My Regionals didn't run Experimental, so I can't confirm. If anyone else can, that'd be great!
What changed, then, is that expectations are now higher for Division B (provided teams actually study the extra stats
). Nothing changed for C from what I can discern. Remember that the scoring explanation on the National site
unpacks the scoring rubric. Under this section, you find a meaty list of 'other relevant statistics'. I'd be competent enough to do multiple of them, especially when you can use a programmable calculator, but, ultimately, do what you have time for. It's hard to say how event supervisor expectation will go here, but the difficulty will fall into the laps of the teams at higher levels of competition where scoring is closer and where one tiebreaker could be which teams did, say, more statistics.
