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

 

Homework and quizzes:

·         Problems will be assigned at every class meeting and will be due the following class meeting. No late homework will be accepted.   Any homework not turned in at the regular class meeting must be deposited in the instructor’s mailbox (Stat Mailroom, Smith 103A) before 12:00pm on the due date. Missing homework will receive a grade of zero.

·         Excel homework exercises must be printed out and stapled to the homework due the same day. 

Only turn in one page with the final solution.

 

·         To receive credit for the homework, 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. Do not use red ink.  Only turn in Excel output corresponding to the final solution.

Not following the above rules will hurt your homework grade.  If you do not write your answers clearly, you will get partial credit.  If you do not staple, do not circle your final answer, write in red ink or do not write your name on your homework, it will not be graded and will receive a zero.

 

·         Homework will not be accepted via email.

 

·         There will be a maximum of six quizzes or pop-quizzes during the semester.  Most of the quizzes will be announced prior to the day given, but I reserve the right to give them unannounced.

 

·         Each homework assignment carries equal weight. Each quiz is worth twice as much as one homework assignment.  In total, homework and quizzes will make up 25% of your course grade.  The lowest 2 homework scores or your lowest quiz score will be dropped.  No late homework assignments will be accepted.

 

·         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 odd problems are in the book.)

 

·         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: 

·         There will be 2 in-class Midterm Exams, each worth 20% of your course grade; the Final Exam is worth 35%. All exams are required.  There will be no make-up exams. Missed exams will receive a grade of zero.

 

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

 

·         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.

 

·         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 by November 15th so that alternative arrangements can be made.

Honor Code: 

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

·         Each student should feel comfortable approaching the Instructor with any problems s/he has with the course.  If there is a problem which cannot be resolved with the Instructor or with which you do not feel comfortable approaching the Instructor, you may confidentially contact the Director of Undergraduate Studies at the Statistics department: Professor Carlstein, 962-1275.
