Class Notes 10/19

Today in class we covered more of Chapter 6. We talked more about z-scores. The normal distribution and what z-scores mean to the normal distribution. We also did some calculator work on how to find percentiles using your TI-84.

Along with the class notes, we went over the latest Investigative Task (Auto Safety). This time the students got an example of a possible report and I asked them to grade the example, to see how the grading works.

We also did some in class work at the end of class working again with z-scores.
