Teaching Assistant and DiscussionsTeaching Assistant and Discussions

We do several things in the two-hour weekly discussions:

• Quizzes which consists of problems selected from the previous week's Homework assignment.

• Students and the TA work through a Practice Quiz.• Students are encouraged to request the TA's help with

homework problems during Discussion.

You must attend Discussion Sections each week, where quizzes are given. TA's hold individual office hours and you are encouraged to go to ANY of those for help, not just your TA. There will be NO Discussion this week. No discussion next Monday.

Academic HonestyAcademic Honesty

You are expected to abide by the academic honesty code as stated in the UCSB General Catalog on all work for this course. In particular, during the exams and quizzes, you are required to work alone and for only the specified time period.

The penalty for the first offense of academic

misconduct in this class will be a score of zero on the exam or quiz. The second offense will result in a failing grade in the course and may result in a referral to the academic judiciary.

Procedures if you suspect your work hasProcedures if you suspect your work hasbeen graded incorrectlybeen graded incorrectly

Every effort will be made to mark your work

accurately. You should be credited with all the points you've worked hard to earn! However, sometimes grading mistakes happen. If you believe that an error has been made on your exam, return the exam to the TA immediately, stating your claim in writing. Your TA will then pass the script to me and I will re-grade the entire paper. Please note that grades can go down as well as up or remain the same.

Under no circumstances will a midterm paper that has been taken away from class be re-marked.

How to do well in the classHow to do well in the class

Statistics is a problem-solving subject. Practice in problem solving, and completing and understanding the assigned reading and homework are essential to success on the exams. Suggestions for success in the class:

• Attend all lectures. I will not “read from the book” and you will not necessarily find the examples from lecture in the textbook.

• Attend all discussion sections where quizzes are given.

• Take all quizzes and exams.

Note 1 of 5E

How to do well in the classHow to do well in the class• Do the reading before attending lecture.• Do the homework. Do your own work. You

may discuss problems with classmates, but don't copy from them. Compare homework answers with solutions posted on the web sites.

• Study and practice solving problems before taking quizzes and exams.

• Spend 15 hours each week.
