Welcome Back!

Here's an electronic copy of the course overview and the first HW assignment sheet for your reference.
(Remember, adjustments in assignments may be made and announced in class.)



Sept. 11th- Quiz on graphs and Euler circuits and paths. Learning goals below and given in class.



Tuesday Sept. 30th- Test on all work so far. Learning goals will be posted below and given in class.



Monday-Tuesday Oct. 20-21st. Quiz on Hamiltonian Circuits

Thursday Oct. 23- HC City projects due by 2:30.

Here's a link to the document I showed you in class with a critical path graph that includes the flexibility of tasks that have some flexibility.
Critical Path Document from Stanford

Wed-Thurs Oct. 29-30- Quiz on Trees and Critical Paths

Friday Nov. 7th: Sorry to be out today! Please do the following in lieu of class:
Read page 99-103, including the spotlight on 103. Do Pg. 114 #51 and 52. “Color the vertices of a grah” means to color (or label) each vertex so that no two adjacent vertices are the same color AND to use as few colors as possible. There will be different ways to color a graph, but if you have colored correctly, you will get the same total number of colors as anyone else who has colored the graph correctly.
And Pg. 69 #43- parts c and d (for review).


Wed-Thursday Nov. 12-13- TEST on Critical paths and Trees


Slides from Green class critical paths


Friday Nov. 21st. Below is the Operations Research Report assignment in case you lost yours.

HAPPY 2015 CLASS OF 2015!!!

January 7-8th -Below are the links to the NYT articles about recent studies/experiments that were done on procrastination and recovery from concussions. We read them and discussed them in class, but you might want to review them again before quiz and tests in this unit.

1. "If You Want to Meet That Deadline, Play a Trick on Your Mind"
Meet the deadline study

Here's a link to the study about impacting your ability to get things done with "tricks" that the NYT article linked above is writing about.
The Categorization of Time and Its Impact on Task Initiation

2. "Limiting Rest is Found to Help Young Concussion Patients"
Limiting Rest for Young Concussion Patients

Friday January 9th- The following links will take you to Medical Journal Websites where you can read about medical studies and experiments. Pick things that interest you and see if you understand some of the statistical talk in the reports and think about how the research will inform decision-making and future research.

The British Medical Journal

The Journal of American Medical Association

FRIDAY JAN. 9th- To: Matt, Peter, Sarah S, Zoe, Keith, Maddie and Carl- I scanned and uploaded the review sheets from class today (Friday) that you missed. They are below and should help you prepare for the quiz next class. (Some pages scanned twice, don't let that scare you ;) I didn't think it was scanning both sides and don't have time to re-do.) We also reviewed some of the book homework due today in class, #32 and #47 were the ones we went over.


Monday-Tuesday January 12-13th- Statistics/Data Quiz- covers Ch. 5 and some of Ch. 6 in your text and class work. Learning goals will be posted below and given in class. Be sure to review your pop quiz too.



Wednesday Jan. 21st- Statistics/Data short quiz
covers some of Ch. 5 and what we've done in Ch.6 in your text and class work. More details given in class.


Monday Jan. 26th
HW- Go on the website, gapminder.org, hit DATA, and pick 4 topics to look at the graphs for. To see the graph, hit the icon with the circles on it on the right of the screen. Study/read each graph and write a few sentences about what the graph shows, why it might be important, and some of the graph qualities that make it a powerful way to describe data. Be ready to share your thoughts and what you wrote with the class. We'll pull up some of the graphs in class.


Monday/Tuesday Feb. 2nd/3rd- MORE SNOW!!!! So...
THURSDAY FEB. 5th- Statistics/Data Test - (TEST MOVED TO TUESDAY FEB 10th for Green class due to SNOW) we do have class on the half day Wednesday, but we will not have the test until Thursday.
Learning goals were given in class and are posted below. Review the learning goals, your classwork, homework, quizzes and text to be fully prepared.



Thursday/Tuesday Feb. 5th/9th- HW after test- Watch this Ted Talk from Hans Rosling. Jot down any questions it raised for you and any "take-aways."
The Best Stats- Hans Rosling-Ted Talk

Make sure your head isn't solely in the snow- keep learning Discretsters!

Friday/Tuesday Feb. 6th/10th- HW-
1. Read and review the Year in Charts article with charts - pick the graph that you think is the most interesting or illuminating/helpful for understanding and explain in a few sentences why. Also record 2 things you learned from the article/charts and 2 questions that you now have based on the article/charts.
2014-Year in Charts

2. Listen to the "How Efficient Is Energy Efficiency" podcast found at the link below and do the following.
a. Record 3 things that you learned from the podcast.
b. Record 3 questions that you now have based on the issues discussed.
c. Without doing/reading more research and digging answer the following- Do you think Arik Levinson is likely to be right, that building energy codes have not reduced energy consumption? And generally that making energy efficient things probably just encourages people to use them more, as much as they can afford, and thus does not save energy? Or do you think that Levinson is probably missing something and that energy efficient building codes and things are reducing energy consumption?
d. Sketch out 3 sets of side-by-side box plots (2 plots in each set, one new homes one old homes) to represent the 3 sets of homes that Levinson compared to come to his conclusion that California's energy efficient building codes have not reduced energy consumption. Label each group, each y-axis, and make the plots compare in a way that would lead him to his conclusion. (Go to 10min30sec into the podcast to listen and re-listen to Levinson describe the comparisons he did.)


Freakonomics Podcast- How Efficient is Energy Efficient


Monday Feb. 23rd. GREEN class- HW - Counting A #7, Exercise 8-3 #1, 3, 4, 5, 11 (Exercise 8-3 are in the second packet)

Since a lot of this unit is out of the book, I'll post a pdf of the slides from class weekly. But remember, the slides are NOT a substitute for class, there's much that we discuss, think about and work that you do on the other white boards and in your notebooks in class that you don't see in the slides.

Below are my solutions to the review problems on the back side of the learning goals. Those of you who were in class did these and we reviewed some together, those of you who were out will want to review these.


Monday/Tuesday March 2nd/3rd- CW/HW after the quiz. Do the 3 problems on the white board (the 5-card hand probability problems) and do Worksheet "Counting E" #1-3.
