Weekend HW

This weekend, please complete the chapter 12 reading questions. If you did not get a paper copy in class, you can find these below. (Some of you may have already done these, as they were posted over the exam week).

Other than that, be ready to hit the ground running when we get back. We are going to move very quickly through chapters 12 and 13; we have to be finished with the "methods of data collection" unit in the last week of February, so that leaves us with 13.5 days to learn the unit and take our quizzes and tests! Rest up, watch the Superbowl (go Seahawks), and come back ready to work!

One thing to keep in mind when you do this homework--you could, of course, just find these specific answers in your book. However, if you spend a little more time to more thoroughly read the chapter, you will likely have a better understanding of everything as we quickly move through our notes in class.
