The test on Chapter 2 is Monday. Bring your calculator. C U at CiCi's if you're up for it! (Behind the Starbuck's on Hwy 92) Have you tried the online quiz?
HW due Friday, Sept 19 (International Talk Like a Pirate Day!!) Work at least seven challenging problems from Chapter 2 that we haven't assigned yet. The more you challenge yourself, the better prepared you'll be for the test on Monday.
HW due Wednesday: Problems 2.51 through 2.54. Chapter 2 test will be on Monday.
HW due Tuesday, Sept 16th: 2.46, 2.47, & 2.50.

Chapter 1 - Exploratory data analysis
We are learning how to create graphical representations of data and to interpret different graphs.
MESSAGE TO AP STUDENTS: It is impossible for you to make up the discussions and interactions that you miss when you are absent from class. Therefore, it is your responsibility to keep up with the homework so you are not behind when you return to class. This means that you need to get the assignments from the blog or another student. Email me if you need more information--but don't show up empty-handed after an absence! You'll only get further behind.
HW for 9/2: Take notes on timeplots and ogives from the text. You will be expected to construct these graphs tomorrow in class. You would benefit from looking through the chapter summary to see if there is anything you don't understand/can't do. The test is THURSDAY!
HW for 8/29: Using the data collected in class, recreate the box and whisker plot, the stemplot, and the histogram representing the data. Look in your book for directions for the following: Back to back stemplots, back to back histograms, and parallel boxplots. Separate your data into boy data and girl data and create each of those graphs to compare the boy data to the girl data.
ALSO, consider the effect of outliers on the mean, median, standard deviation, and interquartile range of the data. Which of these measurements will be affected tremendously by outliers?
Be safe.
HW for 8/27: Bring in a graph that excites you. It must be a histogram, boxplot, stemplot, or other graph that you can write about BUT NOT A BARGRAPH. The graph can be from the newspaper, a magazine (with permission from the owner to cut it out!) or printed from the Internet.
HW for 8/26: Using the data from problem 1.11 in the text, create a split stem-and-leaf graph of the ages of the Presidents at inauguration. Write a few sentences describing what you have created and compare/contrast the results with the histogram that you created in class to represent the same data.
