Day 13: Ch.2.2 - Normal Distribution Calculations
9.25.13
Overview of class today
Today we learned how to perform Normal curve calculations on the calculator, including area under the Normal curve to find percent of the data that falls between a specific range of values and Normal probability plots for assessing Normality. The textbook has tutorials on how to use the graphing calculator to find Normal curve areas on p. 118-119 (if you want to actually draw the picture of the shaded Normal curve on the calculator) and p. 123-124 (if you just want to calculate the area under the Normal curve). I would recommend always drawing the curve by hand, whether or not you get help from the calculator to do it.
Assignment DUE Monday, Sept. 30th, 2013
(1) Finish the Chapter 2 practice AP test in your textbook, p.138-139 (this will be graded!)
(2) Re-watch the video on "Describing Relationships: scatterplots & correlation." Follow along on p. 142-157. Compare your summary notes to mine here.
(3) Complete the practice problems for concepts 1-3 in your Chapter 3 packet (p. 44-46).
(4) Work on your GRASPS! Final draft is due next Friday, Oct. 4th, 2013.

Day 8: Ch.1 AP questions & GRASPS Introduction
9.13.13
Overview of class today
After today, you should feel confident about the content we've learned so far in the course. Additionally, you should understand how the AP free-response questions are scored. To assess your mastery of exploring data (chapter 1), you will work with a partner to analyze real ChiArts data in a GRASPS. Data sets will be ready for you on Monday. The GRASPS is due Fri, Oct. 4th, but a draft is due Mon, Sept. 23rd. The deadlines appear on the senior calendar.
Assignment DUE Monday, Sept. 16th, 2013
(1) Practice AP multiple choice & free-response: textbook p. 78-81 (This will be collected & graded)
(2) We're starting Chapter 2! Watch the video "Describing Location in a Distribution: measuring position." Follow along in the textbook on p.84-91. Complete your SRQ journal (are you actually doing this? It's a good exercise to help you internalize what you're learning and identify questions or confusions!).

Day 5: Ch.1.2 - Histograms
9.6.13
Overview of class today
On the AP exam, you will need to use your graphing calculator effectively in order to save time. Today's class is all about creating histograms using technology. Watch the following videos (made by a teacher friend of mine!) for detailed instructions on how to use the calculator to make histograms: *Entering data in the graphing calculator *Histograms & boxplots on the graphing calculator (we'll learn boxplots next week!) And, if you didn't get enough of it in class, play with this applet to see the effects of histogram bin width on shape of a distribution. Assignment DUE Monday, Sept. 9th, 2013 Part 1: View the "Describing Quantitative Data with Numbers: measuring center & spread" video and complete your SRQ journal. The corresponding textbook pages are p. 50-58. Part 2: Try the multiple choice questions on p. 16-19 of the packet handed out in class today. Then try the FRAPPY! question on p. 20-23. These are real, old AP exam questions! Find a digital copy here. |
Day 4: Ch. 1.2 - Dotplots & Stemplots
9.4.13

Practice makes perfect! We moved around to stations practicing our quantitative data graphing skills. Download the station problems and solutions here. Check out the Prudential TV commercial below for an example of a dotplot. Add your own sticker to the dotplot at the Prudential website.
Assignment DUE Friday, Sept. 6th, 2013
You guessed it...watch the video "Displaying Quantitative Data with Graphs: histograms" and complete your SRQ journal. Follow along on p. 35-42 of the textbook.

Day 3: Ch. 1.1 - Marginal & Conditional Distributions
8.30.2013
Overview of class today
Today we worked with two-way tables and used marginal & conditional distributions to look for associations between categorical variables. We also learned the 4-Step Process: State, Plan, Do, Conclude. Our two-way table with the marginal & conditional distributions of hand washing by gender is at the left.
Test yourself: Which part of the table represents the marginal distribution, and which part represents the conditional distribution? What can we conclude from this analysis?
Assignment DUE Wednesday, Sept. 4th, 2013
Over the long weekend, please watch this video: "Analyzing Quantitative Data: dotplots & stemplots." Complete your SRQ notes. The corresponding pages in the text are p. 27-34.

Day 2: Chapter 1.1 - Analyzing Categorical Data
8.28.13
During this unit, we are experimenting with a "flipped classroom." This means instead of listening to a lecture and taking notes during class then practicing problems outside of class, you will watch a video lesson and take notes outside of class and then practice problems with the support of your teacher and classmates during class. It might take some getting used to, but I'm confident this will be a more effective way to learn and master the content to best prepare you for the AP exam!
Assignment DUE Friday, 8.30.13
Watch this video lesson on "Analyzing Categorical Data: marginal and conditional distributions." Remember to take notes in your journal and reflect using SRQ (Summary, Reflection, Questions). If you can't access the video or want a supplement, please read your textbook,The Practice of Statistics (which I'll refer to as TPS), p. 12-17.

Overview of class today
We watched our first video in class today on "Analyzing Categorical Data: bar graphs & pie charts" to model best practices while viewing videos. For more fun with graphs of categorical data, answer the poll at the right! Why is "pairs of shoes owned" a categorical variable in this case? |
