Schedule at a Glance (click here for schedule archives)


M 5/15/00

Work in class on designing the STA student survey for 2000-01. The original Nov. 1999 survey is available in Microsoft Word and HTML formats. We will divide into small groups to generate good ideas. Let’s make a survey that is much better than the one that was administered in November 1999!


T 5/16/00

Steering committee finalizes criteria for groups to use when writing surveys. Groups will meet for second half of class.


W 5/17/00

Field trip to National Cryptologic Museum at NSA, Fort Meade, MD. Meet at bus loading area next to the gym at 9:00 a.m. sharp. We will leave at 9:05 a.m., so don’t be late. You will be excused from your B, C, D, and E periods if you come on the field trip. F period class will be held at the normal time for those who do not attend the field trip. In order to avoid an unexcused absence, you must do at least one of the following:

1. Attend the field trip. (If your other teachers give you their permission, you can do this even if you have not already signed up.)
2. Or, attend the F period class to work on your survey project. (This is not required for those on the field trip, obviously.)
3. Or, if you miss both the field trip and F period class, work the alternate problem.


Th 5/16/00

Work on survey project. Be sure you follow the D period or F period guidelines approved by the steering committee for your group. For your convenience, the original Nov. 1999 survey is available in Microsoft Word and HTML formats.


F 5/19/00

Last day of class. Final survey project (100 points per person) is due. Grading criteria are as follows and will be equally weighted:

1. Quality of questions (e-mail or Microsoft Word floppy disk format strongly preferred).
2. Quality of methodology write-up. Consider such issues as ensuring coverage of subjects, reducing response bias, describing randomization or stratification (if any), time and day of survey, etc.
3. Quality of conformity to the steering committee’s guidelines. Note that D period and F period guidelines differ. You are responsible for conforming to the guidelines for the group to which you are assigned, regardless of the class you are enrolled in or normally attend.

For your convenience, the original Nov. 1999 survey is available in Microsoft Word and HTML formats.

Individual submissions are acceptable and may be advisable in cases where your group partners have ended their senior year early. However, group submissions will be easier, better, and are encouraged provided you state in writing what each person did.


Th 5/25/00

Final Exam, 2:00 p.m., Trapier Theater. Anyone with a B (or higher) semester average who has already taken the AP exam is exempt from taking the final exam. Seniors with a B semester average are exempt even if they have not taken the AP exam. Anyone with a semester average below B must take the final exam, regardless of AP exam status. If you think you might be in danger of having to take the final exam, send e-mail and I will reply with your scores as soon as they are averaged.


F 6/2/00

Prize Day: Please turn in your copy of How to Lie With Statistics if you have not already done so. The best time is from 3:30 to 4:00 p.m. in Room S. If you prefer to purchase your copy, please bring a check for $9.00 payable to St. Albans School.





Essential Links:
-- College Board: AP Statistics Main Menu
-- RVLS (Rice Virtual Lab in Statistics): One of the best sites anywhere for statistics! Here you'll find a complete college statistics course (complete with clickable glossary and great case studies), simulations (for example, click here or here to see balls falling through a grid of nails), and some excellent analysis tools.
-- WebStat 2.0: An on-line statistical computing package (requires Java)
-- How to study statistics (written by an Australian university professor, but the ideas are valid for our class)

TI-83 Links:
-- TI-83 programs from Texas Instruments
-- More TI-83 programs (untested)

Fun Links:
-- Guess the correlation coefficient! My best score so far for 5 scatterplots is 0.9957. Can you beat this?
-- Another correlation game (takes longer to load, but allows you to achieve fame if you score in the top 20 worldwide)
-- Least squares regression game (requires Java): After the Java applet loads, click the "?" icon in lower right corner for instructions.
-- Photos from our 5/20/99 field trip to the National Cryptologic Museum at the NSA
-- Huge Internet gallery of statistics jokes (warning: many are excellent, but some are dangerously lame)
-- Average age at death for rock stars is 36.9 (vs. 75.8 for the overall population). . . this site is religiously oriented (and apparently sincere), but the reasoning process is seriously flawed. Can you find the problem?
-- A formal mathematical proof that approximately seven shuffles are required for good randomization of a 52-card deck (note: requires Adobe Acrobat Reader)
-- Chance Database Welcome Page (this is the link cited in the 4/4/99 Washington Post Unconventional Wiz column)
-- Accident statistics (the taxicab problem)
-- Psychological probability quiz
-- Marilyn is Wrong! (a truly great site, even though it doesn't seem to include Dr. Morse's response to Marilyn yet)
-- Use of Chips Ahoy cookies in statistics
-- The amazing Banach-Tarski Paradox, which apparently permits any sphere to be cut and reassembled into two spheres, each having the volume of the original sphere
