Padlock on Toilet Paper

I took this picture a year ago at a local fast food chain.
So what questions come up?

Feel free to use this pix in your lessons. If you do a wcydwt style lesson with this pic, I would appreciate it if you shared it with me. I won't have time to play with this until summer.

Note: This is posted here after a #statbook discussion where expected value came up. An example in the book we were reading reminded me of this picture. When I took this picture a year ago, I planned to include it in a lesson on expected value in AP Stats but I never got around to it and forgot that I had it. I need to blog more to remember to do things.

Just added WeatherSpark to Tools. WeatherSpark allows you to visualize graphs of weather data. Great for getting data and graphs for a statistics class. Here's a sample showing the periodic nature of seasonal changes in temperature.
