amount of data available in the world.
 Used to make rational, scientifically
based decisions.

Course Requirements
 1. Textbook: The Practice of Statistics
(3rd ed). Please keep safe!

83/84)
 3. Notes: You may find it helpful to print
out the powerpoints beforehand and add
to them as you feel it’s necessary.
Grading and Goals
 75% major assessments (chapter tests)
 25% minor assessments (HW completion,
graded OE questions, and do-nows)
 GOALS





At least 50 students take the AP test.
At least 8 students score a 5
No student scores a 1
At least 85% pass the exam (3 or higher)
Average Score above 3.60
What is considered
cheating?
 Looking at someone else’s test paper.
(Classroom is full…no wandering eyes)
 Relaying information about tests to
students in another block.
 Requesting test information from AP
Stats alumni.
 Copying and sharing HW answers, (both
nightly assignments and graded OE’s).
What is not considered
cheating?
 Working with one other person on a graded
HW assignment…. as long as both students
are actively involved in crafting the response.
(Write your partner’s name on the paper).
 Looking up old AP questions online
(apcentral.collegeboard.com) which resemble
the one assigned.
 I value your integrity and hard work more than
your test score.
Expectations
 Your intention should be to take, and
pass, the AP Exam.
 Disruptions caused by students (usually
seniors) that decide not to take the exam
will not be tolerated.
 You will study regularly outside of class,
especially over spring break.
 Perfect attendance from now until May
9th.
