Class notes 11/12

Today in class we went over the assigned homework. Again chapter 7 was about what kind of information can we get out of a scatterplot. We can tell things like the association of two quantitative variables (positive or negative), is the association strong, moderate or weak and other things.

After we went over the homework the class completed a handout again looking at scatterplots and seeing what kind of information you could get from it.

When the handout was completed we briefly took notes on the beginnings of Chapter 8. In this chapter we are now going to take the information we learned in Chapter 7 and use mathematical equations to help us find more information on the data we are looking.

For homework due 11/16: Read Chapter 8.

Class Notes 11/3

Today in class we worked more on z-scores and what we can get from them. We worked on some examples that had to do with trying to find percentiles, and then we also looked at some examples where we knew the percentile and we had to work our way backward using the InvNorm function on our calculator.

Homework due 11/3: Page 132 # 39-47 odd, and read the beginning of chapter 7 (scatterplots)

Class Notes 10/30

Happy Halloween everyone.

In class we worked on Normal Percentiles and how we use z-scores to figure out the percentiles.

Homework due Tuesday 11/2: page 129 # 5-17 0dd, #25-29 Odd, and #37
