I try my best to avoid threads that turn into arguments, but I think I realize the problem underlying this disagreement. I think it is a matter of semantics and what exactly GFOA means by "facts" which I don't think is as straight forward as he believes. He didn't clearly say what was meant by a 20% improvement so I don't agree that others would be at fault if he didn't convey his point well. Of course the blatant disrespectful tone and insults to others' "analytical abilities" doesn't help the discussion.
One of the oldest message board tactics is for a poster to provide a very limited explanation and then insult others for not understanding what was the original intent. Not saying with any certainty that was the case here, but maybe with more explanation the confusion could have been avoided. As Bo preaches to the football team, maybe it would be better to point the thumb first before the finger?
Anyway, I'm no statistician but I've had a few graduate classes in research statistics. I'm by no means an expert but here's my attempt at a breakdown of what I see is a confusion of numbers.
The problem in the discussion as I see it is what you meant by increasing the percentage by 20%. Did you mean 20% in each category, 10% in each of the 2 categories, or 20% of combined 3rd and 4th down conversion percentages? Those have very different statistical meanings. After looking at Husker Mort's post I think I see where you get the 20% numbers
Third Down Conversions
Wisconsin: 84/170 - 49.4%
Nebraska: 79/194 - 40.7%
Difference = 8.7%
Fourth Down Conversions
Wisconsin: 6/10 - 60.0%
Nebraska: 8/16 - 50.0%
Difference = 10.0%
Combining the separate percentage differences would be 18.7% which is where I think you get the 20% figure. However, taking the two statistics together for combined 3rd and 4th down conversion percentage would result in Wisconsin: 90/180 = 50% and NU 87/210 = 41.4% which is a difference of only 8.6%.
I agree that improving 20% in combined 3rd and 4th down conversion percentage would be huge, but you weren't exactly clear in your responses about what you were referring to as a 20% improvement. I think some people believed you were referring to a 20% improvement in 3rd down conversion percentage and 4th down conversion percentage separately, leading to what was believed to be a distortion of the facts? I don’t know, just guessing and I don’t want to speak for others.
Now, if you separate them two figures and add 10% to NU's 3rd down efficiency it would be 50.7 to Wisconsin's 49.4 and adding 10% to NU's 4th down efficiency would mean both teams would be at 60%. Hence the percentage values would be nearly equal, still a big improvement for NU that likely would have a significant impact on the number of W’s, but not as significant as in the case of 20% improvement in each category separately.
For argument's sake, if someone thought you meant a 20% increase in 3rd down conversion in addition to a 20% increase in 4th down conversion, that would make the numbers look like this:
NU 3rd down conversion = 60.7% Wisconsin = 49.4%
NU 4th down conversion = 70% Wisconsin = 60%
Now that would be a substantial improvement to say the least...
Have I confused anyone else besides myself?
haha
Maybe this could have been avoided if GFOA stuck with “the facts” and provided a thorough explanation before resorting to insults and negativity?
