COURSE OBJECTIVES In this class, students will: 1) increase their knowledge of both descriptive and inferential statistics; 2) familiarize themselves with Excel. COURSE WEBSITE This course has a website on Blackboard. You will have to self-enroll in the site. To do so, go to: http://blackboard.cornell.edu/. Click on "For Students." Then click on "How to Self-Enroll in a Blackboard Site." I will post my lecture notes and selected overheads on the web site by 5:00 pm the day before class. You should print out the materials and bring them to class. Book problem sets, computer problem sets, problem set solutions, and other materials will also be posted on the web site. I will post announcements on the web site stating what you should print out for class and when assignments are due. SECTIONS You must be registered in one of the sections. Section attendance does not count towards your grade. The TA will go over the problem sets and answer any questions you may have on the material we cover in class. The TA will not cover any new material in section. COMPUTER LABS We will meet in the computer labs in Mann B30A and Mann B30B on: Fri Sept 19, Fri Oct 17, Fri Oct 24, and Fri Nov 14 (1:25-2:40 pm on each date) The computer problem sets involve Excel. I will post the data sets we are going to use on the web site. You do not need to bring anything to save your work on. It is easier just to email your work to yourself if you want to work on it after class. You can do the computer problem sets on your own if you can't make it to the labs on those Fridays.
COURSE MATERIALS The textbook for the course is Moore, McCabe, and Craig (Sixth Edition) Introduction to the Practice of Statistics. You will need the textbook to complete the problem sets. If you do not want to buy the book, a copy is on reserve in the Mann Library. You will also need a calculator for this class. You can use any type of calculator. EVALUATION Grades are based on the following distribution: Problem Sets (book and computer) Prelim #1 Prelim #2 Final Exam (cumulative) 15% 25% 25% 35%
Prelim #1 will be Thursday, October 2 from 7:30 pm 9:30 pm. Prelim #2 will be Thursday, November 6 from 7:30 pm 9:30 pm. The Final Exam will be Tuesday, December 16 from 7:00-9:30 EXAM pm. POLICIES You must take the Final Exam on the date and time specified above. If you cannot take the Final Exam on the date and time specified above, then you should register for a different Introduction to Statistics class. Only people with official university types of reasons can take a makeup exam for any of the exams (see http://cuinfo.cornell.edu/Academic/EXSP.html#rules). Please note that a job interview is not a university-sanctioned excuse for missing an exam. All exam times are set by the university and cannot be rescheduled. If you are going to miss an exam for an official university type of reason, please email me before the day of the exam. Once you take an exam, under no circumstances are you then permitted to take a makeup of that same exam. If you feel you are too sick to take an exam, do not take the exam. Instead, go to the doctor's and get a note stating that you were too sick to take the exam. If you are forced to stop attending class in the middle of the semester due to a medical condition and you take an incomplete, all of your exam scores from the exams you took during the semester will count towards your final grade. GRADING POLICIES All problem sets should be handed in at the beginning of class on the day they are due. Problem sets will be accepted late only for official university types of reasons. If you think that an exam has been graded incorrectly, bring it to me. Final grades will be decided on the following scale:
A+ A AB+ B BCs Ds F
97-100 93.0-96.999 90.0-92.999 87.0-89.999 83.0-86.999 80.0-82.999 70.0-79.999 60-69.999 Below 60
All students are expected to abide by the Cornell Code of Academic Integrity (see http:// www.cornell.edu/Academic/AIC.html). CLASSROOM POLICIES Class starts at 1:25. Come to class on time. Make sure your cell phones are turned off during class. Do not text during class.
