Cox Mill High School Hunter Thompson AP Statistics hunter.thompson@cabarrus.k12.nc.us (704) 788-6700 ext. 2113 Classroom Guidelines / Expectations Obey all school-wide rules. Participate in class. Stay awake and alert. Work “bell-to-bell” on math. Do not have work for other subjects out on your desk. Show courtesy, respect and good manners at all times. Bring materials to class every day (text book, pencils, paper, homework, calculator) Homework will be assigned every night. Do it. Show integrity. Do your own work. Do not copy another person’s work or give your work/answers to someone else. Course Description This AP Statistics course is taught in a 4 by 4 structured school. Our students take 4 classes each semester on a block (90 minute) schedule. AP Statistics is offered second semester, which usually starts the third week of January. My students are generally in class for 13 weeks prior to their exam. Therefore, this course is taught at a brisk pace and broken into 14 chapters. During this time we will look into and interpret graphs, calculate probability, work to understand statistical inference through confidence intervals, as well as much more. Materials Three-ring binder with notebook paper, graph paper, section dividers Pen, pencil, highlighter 3 x 5 note cards A graphing calculator (TI-84 or TI-89) is necessary for homework and class work There is a course fee for stats. In lieu of me collecting this money, I will instead have you each buy a review book. 5 steps to a 5: AP Statistics By: McGraw Hill Assessment / Grades Your performance will be evaluated through various means of assessment including tests, class work, homework quizzes, group work, projects, and other written assignments. Study for tests. I never give “re-tests”, so be prepared on test day! The AP Statistics Exam Save the Date: May 6th or 13th This will be the day that your statistical knowledge will be put on display, so be ready! With a good enough score, you will receive college credit. The score needed is a 3 for most state schools. Exam Content The exam is three hours long and covers a one-semester introductory non-calculus-based college course in statistics. In Section I of the exam, students are given 90 minutes to answer 40 multiple-choice questions on a wide variety of topics. In Section II, they must answer several free-response questions; each exam contains four to seven open-ended questions designed to be answered in about 10 minutes each, and a longer investigative task for which 30 minutes is allotted. The following major topics are covered: Absences / Make-Up Work On a day when you are absent from school, email me before noon, call a classmate, or check the website to get your assignment. Do your own make-up work within five days. Do not copy someone else’s work. Copy the notes you missed from a classmate. If you are absent on a test day, you will make up that test during class the first day you return to school. Discipline Follow directions and exhibit good behavior at all times. Failure to comply will result in parent contact, detention, referral to an administrator Extra Help Have integrity when working together on assignments. Ask your classmates for help, but do not copy some else’s work or allow others to copy your work. Tutoring will be during TEAL Time.
