ONE QUESTION YOU CANNOT ASK ME:
What did we do in class? Please ask someone else in the class.

I DO NOT GET INVOLVED IN ENROLLMENT MATTERS. If you would like to enroll in the class, you have to do so through the usual method via the registrar. Switching sections is not permitted unless you can find someone to switch with you, in which case you should both go see (or email) the Statistics Department Staff and ask them to switch your sections.

Tests.
Midterm is Thu Aug31, 10am-11:50am.
Final exam is Thu Sep14, 10am-11:50am.
Exams are online, open book and open note, but no communicating, email, or web browsing. Have a calculator ready. There will typically be no make-up exams. If you have a conflict and cannot take the exams, do not enroll in the course. Those who cannot take an exam because of an emergency must meet with the instructor to make special arrangements.
Students with special needs must consult with the instructor by the second week of classes if special arrangements are required.
Cheating will absolutely not be tolerated. All homework and exam problems are to be solved independently. Anyone caught cheating will automatically be subject to appropriate University disciplinary action.

GRADING:
Homework (15%)
Lab assignments (10%)
Midterm (35%)
Final exam (40%)

If you want to switch lab Sections, you need to find someone to switch with you. You will then both need to see an administrator in the main Statistics office and she will help you two formally do the change.

Gradegrubbing procedure: if you would like a question (or more than one question) reevaluated, submit your exam or homework and a WRITTEN explanation of why you think you deserve more points and how many more points you think you deserve to me, by email. Do not complain to me about your grades or ask me to re-evaluate your grades verbally during the zoom or in office hours. Instead, I prefer it to be by email.

HOMEWORK:

Homeworks must be turned in when lecture starts. Homeworks may be submitted early, at any time, by email. Homeworks will be given scores between 0 and 10. Those turned in between 5 and 10 minutes late will be given a one-point deduction. Those turned in 10-15 minutes late will be given a 2-point deduction. Those turned in 15-30 minutes late will be given a 3-point deduction. Those turned in 30-50 minutes late will be given a 4-pt deduction. Those turned in 50-110 minutes late will be given a 5-pt deduction. NO HOMEWORKS will be accepted at all after class. PLEASE INCLUDE YOUR SECTION CODE AND YOUR SECTION TIME ON ALL HOMEWORK ASSIGNMENTS.
