Are you nervous when you see NCWEE? concerned when you see CIRC? perturbed when you see PBC? Visit Mr. Hansen’s fabled abbreviations page to make sense of those cryptic markings you see on your papers.

Written assignments should follow the HW guidelines.


F 5/21/04

Last day of school. I have decided, after some reflection, to offer the following challenge. If Zach and Michael (and everyone else, too, by offering study assistance and moral support) can bring the class pass rate on the Must-Pass Quiz to 100% by the end of this class period, then I will purchase STAtistics Must-Pass Quiz T-shirts for everyone. (Artwork to be determined.)


W 5/26/04

Final Exam, Steuart 101/102, 2:00–3:00 p.m.  Bring calculator, spare batteries, and several pencils, but no paper. Anyone is welcome to take the exam, but the exam is required only if your second semester average is below 80%. The exam will count as 20% of your semester grade. However, if you have passed the Must-Pass Quiz before the start of the exam, the exam will be scored only if it helps your average.

Late-breaking change: Because the projects were uniformly of high quality, I have decided to make the exam optional for everyone. Furthermore, your exam score will count only if it improves your semester average. Therefore, you have nothing to lose. The format will be 27 questions, multiple choice, with calculator. Time limit is 1 hour, or 1½ hours for extended time.

Controversial Links:
-- Does an elite college really pay? Article addresses the issue of whether you would do better financially if you simply invested the difference in tuition price.

-- 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?
