Welcome to the STAtistics Zone

(AP Statistics, Periods D and F)

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.

Schedule at a Glance (click here for the overall schedule)


F 5/11/01

Review day (attendance required except as noted below*). You will need to record your nightly practice problems on a log sheet. This applies to everyone, even those who are not taking the AP exam, because this is a team effort.

* Attendance is not required for people who have submitted a cut notice by e-mail, for D period students who have an 8:00 a.m. AP exam, or for F period students who have a 1:00 p.m. AP exam. Brian Rabbitt, who requested dispensation from D period for a valid reason on Friday, is excused. Others who failed to appear for class but did not make a request have been reported to Mrs. Selinger as unexcused and have been charged 40 points. If you are not taking the AP exam, you are still required to attend in order to boost your classmates as they prepare.


M 5/14/01

Review day (attendance mandatory except as noted above*). Multiple-choice results from the practice AP exams are now available.

HW due today for everyone: First spot check of log sheet.


T 5/15/01

Field trip to the National Cryptologic Museum, Fort Meade, MD. Board bus on service road near gate at Garfield St. before 8:45 a.m. We will be back by about 1:00 p.m.

The field trip is optional. However, if you do not attend, you must go to your other classes. Only those who actually attend the field trip will be excused.


W 5/16/01

Review day (attendance mandatory except as noted above*).

HW due today for everyone: Second spot check of log sheet.


Th 5/17/01

Optional class period. This is a chance for you to get any lingering Islands of Uncertainty resolved before the exam.

AP Examination: NOTE CHANGE in starting time. The exam will start at approx. 2:40 p.m. (i.e., 15 minutes after the end of Senior Chapel, which is required for everyone).


F 5/18/01

HW due today for everyone: Final submission of log sheet. Also, if you have not already turned in your copy of How to Lie With Statistics, be sure to bring $9.00 so that I can purchase a replacement.

Last day of class: Finalize the "20-Year Curriculum" and say farewell.


Th 5/24/01

Final exam, 2:00 p.m., Trapier Theater. Anyone with a second semester average of 80% (B) or above is exempt. Also, anyone who took both versions of the practice AP exam is exempt, even if the second semester average is below B.
