  1. Let's say you spent 12 hours awake today. That means out of 24 hours, you spent
  2. 12 hours asleep. And let's say you spent 24 awake. That means you spent 0 hours
  3. asleep. if we graph this for everyone, all of you will fall somewhere along
  4. this line. We're assuming that you can't be half-awake or half-asleep. And in
  5. that case, r is negative one. But normally, we deal with data that is not
  6. perfectly correlated. And we can't calculate it in our heads. Instead, we'll
  7. use software, and we can do it with Google Spreadsheets. Yay!
