A while ago k8nowak was looking for exponential data besides credit card loans and bacteria growth. Take a look at the data describing visits to my (very new) blog:
Looks a lot like exponential decay to me. In retrospect, I’m almost sad to have posted and ruined the trends. But, for those of you with very popular blogs, I think you might have an interesting option here. Have students create a webpage, right, for any old reason – to review multiplication tables or explain the distributive property or whatever. They could even just post their drawings, a math joke, short stories, whatever. When they’re done, link to it from your blog! Do it early in the morning so you don’t get the weird bump at the front edge like I did. They’re not likely to get a lot of other traffic, so I think the data might be cleaner than mine.
This is risky if you are banking on the graph being exponential, but if you’re open to a class discussion about modeling traffic, where exponential curves will probably, but not definitely, come up, I think this would be fascinating. You know, you could guess how many visits will come the next day… and then see how close you are! Would this be more interesting than loans and radioactivity?
I’d be interested in hearing from other blogs who notice peaks in traffic when someone famous gives you a reference. Is the curve always exponential decay?
