Attendance:   An attendance sheet will be passed around during each class meeting.  Attendance is required but will not be given a grade. Be on time. Turn off your cell phone in class.

 

Homeworks, quizzes and class project:

Ø       Problems will be assigned at each class meeting and will be due the following class meeting. No late homework will be accepted.

Ø       The class project will consist on four assignments. These assignments are not independent of each other.

Ø       Any homework or class project assignment not turned in at the regular class meeting must be deposited in the instructor mailbox (Room 117, New West) before 12:30am on the due date. A grade of ZERO will be given to MISSING homework or class project assignment.

Ø       There will be a maximum of five quizzes or pop-quizzes in the semester.

Ø       Excel homework exercises, along with auto-tutorial instructions, can be found at http://www.stat.unc.edu/teach/rosu/Stat31/Companion.html.

Ø       To receive credit for the homework, the quiz or the class project, you must show all work neatly, clearly LABEL each problem, CIRCLE your FINAL ANSWER, and STAPLE the entire assignment together in the correct order with your FULL NAME printed on each page. Only turn in Excel output corresponding to the template requested in the assignment—do not turn in additional output. Not following the above rules will hurt your homework: If you do not write your answers clearly (homework, quiz or class project), you will get partial credit. If you do not staple or do not write your name on your homework, you will receive a grade of ZERO for your homework.

Ø       Each homework assignment carries equal weight. Each quiz is worth double of a homework. Each class project assignment is worth double of a homework. In total  homework, quizzes and class project will make up 30% of your course grade.

Ø       You may work with other students on the homework assignments. Verbatim copying of homework is NOT allowed and will constitute a violation of the Honor Code. Each student should produce his/her own work to be graded.  After attempting the problems, a student is encouraged to seek help from the Instructor during office hours or from Open Tutorial Leaders during Open Tutorial Sessions.  (The answers to the even problems are in the book.)

Ø       Any questions regarding homework grading should be discussed first with the Instructional Assistant. If you are absent when a homework is returned, you may obtain your homework from the Instructional Assistant.

 

 Exams: 

Ø       There will be 2 in-class Midterm Exams, each worth 20% of your course grade; the Final Exam is worth 30%. All exams are required, and there will be no make-up exams. Missed exams will receive a grade of zero.

Ø       All exams are closed book and closed-note with no formula sheet permitted. Computers are not permitted, but calculators may be used.

Ø       Any questions regarding exams may be taken up with the Instructor. If you are absent when a test is returned, you may obtain your test during the Instructor’s Office Hours.

Ø       Any student needing to be excused from the regularly scheduled Final Exam because he/she has 3 final exams within 24 hours must obtain a written Dean’s excuse and discuss the situation with the Instructor at least 3 weeks before the regularly scheduled Final Exam, so that alternative arrangements can be made.

Ø       Course grades will be posted on the Instructor’s web page. Each student is responsible for verifying his or her recorded scores during the semester.

Ø       The Honor Code will be observed at all times in this course.

Ø       This course will participate in a Departmental Course Evaluation.

Ø       Each student should feel comfortable approaching the Instructor with any problems he/she has with the course.  If there is a problem which cannot be resolved with the Instructor or with which the student does not feel comfortable approaching the Instructor, you may confidentially contact the Director of Undergraduate Studies at the Statistics department: Prof. Budhiraja, 105 New West, 962-2189
