TEXT: Tintle N, Chance BL, Cobb GW, Rossman AJ, Roy S, Swanson T, and Vanderstoep J. Introduction to Statistical Investigations, Wiley, NY.

INSTRUCTOR: Frederic Paik Schoenberg
Email -- frederic@stat.ucla.edu
Office -- Slichter 3873.
Office hours -- Wed after class, on zoom.

Lectures on July 7 and July 9 will be recorded in advance and links will be placed on the course website, and there will be no 11am zooms on those two days. The other lectures will not be recorded. For all my lectures, I will always be putting the lecture slides on the course website.

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

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.

I do not give hw hints in office hours or by email. Conceptual questions only. However, during lecture I am fine with giving hw hints and answering questions regarding hw.

Tests.
Midterm is Wed Jul16, 11am-12:50pm.
Final exam is Wed Jul30, 11am-12:50pm.
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.
Other than the exams, attendance during lectures and sections is not mandatory, but very strongly recommended, and I sometimes give hints and tips regarding the exams during my lectures.

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 (30%)
Final exam (35%).
Better of midterm and final exam (10%).

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.

IF YOU ASK ME TO RECONSIDER YOUR GRADE, IT VERY WELL COULD GO DOWN!!!

This course is part of the UCLA Inclusive Access program. Your course materials are being automatically provided to you, digitally, through Bruin Learn by the first day of class or upon enrollment. The materials are being provided at a reduced and competitive price. You will receive e-mail from the UCLA Store (UCLA Store @verbasoftware.com) with program details and cost sent directly to your email address on file with the Registrar. It is your responsibility to read all communication coming from the bookstore. Check your spam folder if not received.

Everyone enrolled in this course is automatically a participant to start and will have access to the materials through 1st week of class. Those remaining in the program after 1st week will be billed for the materials directly to their BruinBill account and will continue to have access to the course materials. If you do not wish to participate in Inclusive Access, you must opt-out by the Friday of 1sd week deadline or you will be billed. Those who opt-out will lose access to the digital materials and will be responsible for obtaining the materials on their own.

Do not pay for your materials through the publisher website unless you are opting out of Inclusive Access. All Inclusive Access course materials will be billed to your BruinBill account.

Any questions regarding the Inclusive Access program can be directed to inclusiveaccess@asucla.ucla.edu.
