This course offers office hours from different members of the course
staff that are held at throughout the week at different pre-schedules.
Detailed information can be found in the course staff
portion of the syllabus.
For class discussion, we will use a GitHub repository and its issue
system. This forum will be private and restricted to those in the course.
It is very important that each student
- registers a Github account (unless they already have one); such a Github account
is generally different from the U of I Netid
- let the instructors know about the Github id so that we can invite
the student to the (private) course discussion project
See below for recommendations on form and content.
Before you start writing an e-mail to a member of the course staff please make
sure your question is not:
- Already answered in this syllabus or course
FAQ: the syllabus serves as the guiding document for the
course and we are unlikely to shift from it.
- About exercises or homework: please ask the question on the
discussion forum so that all students have access to the answer.
- A technical issue or code error
- Try to google the error verbatim (e.g. copy and paste it into Google).
- Many error messages that you will encounter have likely been solved by others.
- StackOverflow and similar forums can be helpful.
With these cases addressed, please ensure your e-mails meet the following
- The e-mail must be sent from an
@illinois.edu account. Please do
not use another account such as Gmail as we may be unable to
associate that with your account.
- The start of the subject line should contain the tag:
and should be followed by a space and a helpful brief description of
- A good Subject line would be “[STAT 430] Cannot load data file:
error …” whereas “[STAT 430] Need help” or “[STAT 430] Code not
working…” are bad examples.
- Use the course Staff E-Mail address is
to reach all members of the course team.
We will try our best to respond within 24 hours. Homework questions
sent the same day a homework is due will likely not receive a response
before the homework is due. Plan accordingly.
Discussion forums and emails are helpful tools to receive assistance,
particularl if common discourse rules are followed. As the forum
serves as an extension of the course, students are expected to conduct
themselves in an appropriate manner. While writing on the discussion
- Be kind to others: Avoid using explicit, aggressive, or sarcastic language.
- Provide a concise issue title that provides a clear indication of the contents
of the post.
- Phrase titles as “ggplot2 x-axis labeling incorrect” or “receiving an NA value as the final computation”
- Avoid “plot error” or “what’s going wrong here?”
- Format the body of the post so that the issue is shown at a glance.
- Ideally provide a mcve – a minimally complete verifiable
example so that your question can be reproduced.
- Questions regarding code issues on homework must contain modified code
that is as general as possible.
- Avoid putting code verbatim on the forum that can be used by other students
to solve an exercise.
- This will put you at risk for an academic integrity violation.
- Consider visiting Office Hours for help!
At any time, content can be removed from the forum without warning
by anyone on the course staff if it is found to be in violation of these rules.
