Required Text: Introduction to Statistics and Data Analysis. 3rd edition by Peck, Olsen, and Devore. Duxbury, Belmont, CA, 2005. Take the time to read the text!

Required Calculator: The TI–83, TI-84 and TI-89/TI-92 are acceptable for this course. TI-89/TI-92 users should see me at the end of the first class to determine if you have the appropriate operating system and statistical programs. The TI-83 and TI-89 handouts are on my website – you should download them before the next class. The TI-84 works like the TI-83 and the TI-92 works like the TI-89.

Software Usage: Throughout the semester we will be using a statistical software package called “Fathom.” The software is available on any campus computer. You will be required to use Fathom on certain homework problems (see the list of homework problems for the requirements).

Grading: Homework Notebook 20% Exams (4) 80%

Grading scale: I use the standard cutoffs of 90 (A-), 80 (B-), 70 (C-), and 60 (D-). Any curve (and there hasn’t been one before) or adjustment would be used at the end of the semester, not on a single quiz or exam.

Homework problems from the book will be provided at the beginning of the semester. Additional problems will be assigned as needed. You are to maintain a notebook with all of your work/Fathom/calculator output. At the time of each exam, you are required to submit your homework notebook. Your homework grade will be based on the effort made to solve the problems relevant to the material covered on that exam. While your answers need not be correct, doing half of each problem will not result in a high grade.

Please bring your notebook to class and for office hours. This will allow us to examine what you have tried so that we can see if you are on the right track. Note: it is your job to keep up-to-date with the homework. In-class questions about problems may be asked within three classes of when the material was originally covered.

Each homework notebook submission will earn a 10, 9, 8, 7, 6 or 0. Those handing in a notebook with 50% or fewer of the problems substantially attempted will receive a 0. Each submission will count for 5% of your final grade. Late notebooks will not be accepted, period. Missed submissiona will be assigned a grade of zero (0).

On the Midterms and Final Exam the highest of your four exams will count 25%, the lowest will count 15%, and the other two will count 20% apiece. The Final Exam (date and time TBA) will be cumulative; however, 50-55% of the material will come from the sections covered after the third exam.

Although Class Participation/Effort is not formally listed, a strong effort and attendance record can provide the "benefit of the doubt" for those with borderline grades.

Attendance/Make-up/Missed Assignments -. Attendance will be taken on an occasional basis. If you want to do well in this course, then the first step is simple – show up. I can’t guarantee what you’ll earn if you come to every class, but I’m pretty certain what you’ll earn if you have a lousy attendance record. If you are unable to take an quiz/exam for any reason (including mild illness), you must notify me in advance! This can be done by speaking with me in person, over the phone, or by leaving me a phone-or e-mail message. If your excuse is reasonable, something will be worked out. If you do not speak with me until after the exam, a make-up will be given only in the case of an extreme emergency.

Academic Honesty: The work on the quizzes and exams must be your own. If you are caught cheating, you will receive an F in the course and be reported to the Provost’s Office. I reserve the right to begin expulsion procedures. By the way, each exam has multiple versions, so copying from a neighbor will be an obvious infraction.

Cell Phones and Musical Devices (Walkmen, MP3 players) are to be turned off for the duration of the class. All electronic devices other than your graphing calculator must be turned off during all in-class quizzes and exams. Failure to do so will fall under the academic honesty policies.

If you require help outside of what you can normally obtain, contact the Tutoring Center in Savitz Hall (x4264)

Office Hours/Questions/Extra Help – I will be glad to help you if you need it. Office hours are on a first-come/first-serve basis. When a number of students show up, I may move to the table in the middle of the math office (you’ll see me), or possibly into the math conference room (where you wouldn’t see me). Make sure that you check with in the conference room or with the secretary if I am not available during office hours. If you can’t come during office hours, please set up an appointment with me or send me your question via e-mail. Most importantly, do not wait until you have been in trouble for two weeks to come see me. By that time, most people are so far behind that they can’t catch up.

Students With Disabilities and Special Needs: Please speak with me as early in the semester as possible so that we can make appropriate accomodations for you. If necessary, you can also contact the Office of Special Services in Memorial Hall (x4233).

Final Exam

Homework problems: Problems denoted with an asterisk(*) require you to use Fathom. Include your output with your homework. Failure to submit computer output, where required, will result in a two-point deduction from your homework grade. The following guidelines must be met in order to receive full credit.
1) Answers to problems that require calculator functions beyond the standard arithmetic functions should include the function(s) used, what was entered, and the result. A final answer with no work shown will not count.
2) Legibility – if I can’t read it, it doesn’t count.
3) Complete sentences for those questions that require explanations/justifications.
4) Some questions are worded in such a way that you might be tempted to answer “yes” or “no”, with no supporting reasoning. For example, the question “Are there any unusual features in the plot?” should be answered with a “yes” or “no” with a reason for your answer. You will have to answer this way on the exams, so you need to get used to it now.
