In another thread I posted a comment I have heard from (non-athletic) administrators, "The more we win, the more our attendance drops." Someone took exception to that, so I became curious, and thought I'd test it.
Before continuing, I'm using the 'official' attendance numbers, which every school cooks. I will say that for many of us looking from the home side, it certainly seemed that the students just weren't showing up as much. And that may be key; it may be that us old farts sitting on the home side are showing up like in the old days, but student interest is dropping.
We're working with 3 variables: time; winning; attendance. So I had to think about it to produce something that made sense in just two dimensions, so that I could create a graph. What I chose is [attendance × winning percentage] vs [time]. Some of you math folks, particularly the engineers, might be able to do this better.
Below is the graph; I ran a Peason's on it, and -0.112 came back, which suggest that our attendance, despite playing better football, seems to be dropping about 1.1% per year. It's significant, and it suggests that people are losing interest. Now, the students may be the problem; many work one or more jobs, some are parents themselves, and they often have other interests (a good thing). But if students aren't showing up today, we have to wonder if they'll show up as alums.
