AP Statistics Introduction

Benefits of Statistics  Used in all different subject areas, especially: medicine, science, business, psychology, actuarial sciences, and many more.  Needed to make sense of the incredible amount of data available in the world.  Used to make rational, scientifically based decisions.

Part I: Creating Data  Survey  Observational Study  Experiment  Researching existing data.

Part II: Analyze Data  Individuals: Objects described by a set of data.  Variable: Characteristic of an individual.  Categorical: groups  Quantitative: Numerical value  Distribution: Tells us what values the variable takes and how often it takes these values.

What is the following distribution?  2008:01664  2009:  2010:  2011:  2012:  2013:  AP Grades:12345

Part III: Probability  What is the distribution of data supposed to look like?

Part IV: Inference  Make conclusions.  What can we say about a population based on a sample?

Course Requirements  1. Textbook: The Practice of Statistics (3 rd ed). Please keep safe!  2. Graphing calculator (preferably TI 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 9 th.

AP EXAM  May 9, 2014  40 multiple choice, 6 free response.  apcentral.collegeboard.com  Information about the exam  All past AP open-ended questions along with solutions and grading rubric.  Study these questions on your own. We will only have time to complete a small percentage of them.
