I like my statistics book. I don't have it with me, so I can't give specific examples, although I do remember that one of them dealt with the controversial "butterfly" ballots used in Palm County in Florida during the 2000 presidential election. However, I was confused by a mistake the author made, although maybe some people don't consider it a mistake. At one point in a section about categorical variables, some possible categorical variables are listed for wooden construction (as on a house or whatever) and one example is whether the paint is water-based or solvent-based. Water, as you hopefully know, is a solvent. In fact, it's the most commonly used solvent in the world. So one of the categories includes the other category as a subset. Because I was tired, I was momentarily thrown off by this, but then I realized that it was just a mistake.
My instructor for German admonished us not to "go to the outside." I think he essentially wants us not to use the internet for studying German and to rely on the materials we bought for the class, but it was also sort of in reference to tests that he gives out, which are both open-book and take-home. I'm not sure what to think of this. If it's about the tests, it seems completely reasonable. But otherwise, well, I guess it doesn't matter. I paid quite a bit of money for those books and CD's. Might as well put them to good use.
I'm hungry but I don't know whether to go buy something here or just wait an hour.
