Class Notes 10/28

Today in class I handed out your next assignment, which is the car safety investigative task. After that we did a quick group activity dealing box plots and comparing multiple box plots. After that we spent the rest of class going over z-scores and the normal model (which is a very important topic in statistics). We also went over the 68-95-99.7 Rule which you need to know going forward.

Homework Due Friday (10/30): Car Safety Investigative Task

Class Notes 10/26

Today in class we went over the corrected homework that was turned in last week. We went over the quiz (which went well for the entire class), and then we spent the rest of class going over z-scores. A new concept from Chapter 6, that will play a larger role in Stats as we go forward. We went over the packets that you all completed while I was away at my teacher conference. While most of it was repetitive, it's good practice especially with a topic that we had yet to cover in class.

For Homework Due 10/28: Finish reading Chapter 6.

Class Notes 10/16

Today in class we went over the Homework that was due today, and then we went over more examples in class dealing with describing distributions.

Remember we have our quiz on Tuesday.

Homework: Get ready for quiz. pg. 95 #5-15 odd. Start reading Chapter 6 (pg. 104-107)

Enjoy the weekend.

Class Notes 10/4

Today in class we spent more time covering box plots and understanding the information that you can get from a box plot. We looked at a few different examples. We also looked at the formula for an outlier and an extreme outlier.

For Homework, Due 10/16: Read Chapter 5, page 99 # 26-29, and #34.

Class Notes 10/8

Because my voice was still not back to 100% today, in class I finished covering the symmetric distribution discussion and showed the class how to draw box plots, how to draw multiple ones at the same time so you can compare them and I also showed you how to do them on the calculator.

I also announced that there will be no quiz next week. We are getting close to a quiz but there are a few more things I'd like to cover before I give you a quiz.  Because there is now quiz next week I changed the due date of the investigative task.

Homework due 10/14: Investigative Task (Spending on Education)

Have a great weekend.

class notes 10/7

In class we went over some more examples on how to find Q1 and Q3. We also looked at symmetric distribution and how the mean and standard deviation is best suited for distribution.

HW: I extended the previous assignment to Friday, because we had yet to go over standard deviation and the homework dealt with that.

Class Notes 10/5

Today in class we worked more with summarizing quantitative data and more specifically we went over the IQR and how to find the quartiles (Q1 and Q3). There was some confusion on how to find these quartiles and the book even goes as far as to tell us there are many ways to figure it out. On Wednesday I will go over this and hopefully clear up any confusion that is left. We also looked at a bunch of dot plots and tried to compare three at a time and make some observations based on what we were looking at. It's important to be able to make observations when looking at data (i.e. the 5 Number Summary).

Homework due 10/7 pg. 73-75 7-11 odd, 14, 15-29 odd.
