Textbook

There should be three copies of this book each on 3-hour reserve at DuBois library. In semesters past, some students used an online international version of the 7th edition. The material is identical, except that about 25%(?) of the assignment problems, found at the end of each section, are different. If you use the international version and your instructor assigns as HW problems from the book (which is most likely the case), then be sure that you are doing the correct problems by consulting a printed version (for example at the library reserve). The TAs will only grade the problems from the printed version.

Class Material by Section

Chapter 2: All sections.
Chapter 3: 3.1 - 3.9, 3.11
Chapter 4: 4.1-4.10
Chapter 5: 5.1 - 5.8, 5.10 and 5.11

Prerequisites

Two semesters of single variable calculus (Math 131-132) or the equivalent, with a grade of "C" or better in Math 132. Math 233 is required for this course. However, some necessary concepts for multiple integration or partial derivatives will be re-introduced in the course as needed.

Grading

Final Exam 30%, Midterm 1 20%, Midterm 2 20%. The remaining 30% will be determined by your instructor.
Grading scale: A 90-100, A- 87-90, B+ 83-87. B 79-83, B- 75-79, C+ 71-75, C 67-71, C- 63-67, D+ 59-63, D 55-59, F 0-55.

Exams

The midterms will cover separate topics. The final is cummulative but emphasis on post-midterm 2 material. As with almost all math and stats class, the material is sequential and so material on one exam is built on material of the previous exams. Each exam will contain (tentatively) 4 problems, often with parts. You may bring one standard (8.5 by 11)-inch double-sided sheet of paper to each exam, with your hand-written notes. You may bring a calculator. No devices with internet access are allowed. Since you are making your own one-page study guide for the exam, no fomula sheet will be provided by the instructors. Although Midterm 2 and/or the Final may contain some of the distribution tables that are located in Appendix 3 of the textbook.

Midterm 1: Wednesday, October 11th, 7PM-9PM, ILCN 151 (Eric Hall and Mike Sullivan's Sections 1,2,4,5) and ILCN 101 (Anna Liu's Section 3)
Material for Midterm 1: Chapter 2 and Chapter 3, 3.1-3.8

Make-up exams

If you have a University-approved conflict (see the link in this paragraph) with an exam, you must let your instructor know at least two weeks before the exam. A make-up exam might be scheduled to take place shortly after the regularly scheduled exam. If so, the make-up exam will be different than the original but cover the same material. You will need to fill out the following sheet signed by the Registrar's office, explaining to your instructor why you are entitled to a make-up. Make sure to not book any travel during exams, including the snow-make-up date for the final. Travel is not an excuse to miss the exam. If a last-minute emergency occurs after the two-week deadline, you will need to present to your instructor a note either from your medical provider for medical emergencies or from the Office of the Dean of Students for non-medical emergencies.

Old exams

Below are various exams, without solutions, from Stats 515 in previous semesters. Note that the format, such as number of problems, varies. This is because the course chair also varies. Moreover, the exams dates are not always at the same point in the semester. So for example, some material on midterm 1 from one class might appear on midterm 2 of another class.
