For class block #8 (Tu/W, Sept 15/16), we finished chapter 13 (matched pairs experiments) and covered chapter 3 (categorical data). Here are the notes and homework worksheet for class #8:

• Student Notes Class #8 - Matched Pairs and Categorical Data (Powerpoint Slides)
• 3 Worksheet - HW#8 Graphical Displays with Categorical Data (this is the rest of the HW)
• (We are not doing the "shampoo worksheet", so ignore that)

Here are the PowerPoint slides from class on F/M (Sept 11/14) covering experimental design:

• 13 Notes - Experiments and Observational Studies (Block #7 WEB)

About those counting ants...

If you wish to read a bit more about the ants that count -- including seeing a picture of a couple of the actual ants -- here's a link:

• NPR Blog: Ants That Count

Slight adjustment to homework #6 (assigned on test day, due the day AFTER the test):

• Read pages 293-295
• Ch 13 (page 313), #1abcde, #4abcde [skip #11 and #18]

Our first major exam of the year is coming up on W/Th, Sept 10/11. The multiple choice section will account for 40% of the points, while the free response will count for 60% of the points.

Here is the test review for the first unit (randomness, sampling, and bias).

• Review Chapter 11 - 12 (short version) | Full Version (4 pages)
• Review Solutions

(The "short version" is what was distributed in class -- one sheet of paper, front and back. The "full version" has room to answer each question, but takes 4 sheets of paper. This is available for you to print out on your own, if you wish.)

Here are the notes for the two main lessons during the week of August 31 - September 3:

• 12 Notes - Sampling (class #3) (this class covered terms such as "population of interest", "parameter of interest", "sampling frame", and the symbols mu / x-bar / p / p-hat)
• 12 Notes - Bias (class #4) (this slideshow covers the different forms of bias and includes the examples from class)
