A \(>= 93\), A- \(< 93\), B+ \(< 90\), B \(< 87\), B- \(< 83\), C+ \(<80\), C \(< 77\), C- \(< 73\), D+ \(< 70\), D \(< 67\), D- \(< 63\), F \(< 60\)

Labs

In labs, you will apply the concepts discussed in lecture. Labs will focus on both computation and conceptualization. Lab assignments will be completed using quarto and submitted by pushing your best version to GitHub by the deadline. While you may collaborate with others on lab assignments, your final solution must be your own.

Exams

There will be two take-home, open notes exams. Through these exams you have the opportunity to demonstrate what you’ve learned in the course thus far. Each exam will include small analyses and computational tasks related to the content in labs. More details about the content and structure of the exams will be discussed during the semester.

Final project

The final project allows you to explore a question and data set of your own choosing. More details about the project will be provided during the semester. Projects will be completed in teams.

Quizzes

On random class days, there will be a brief quiz on the previous lectures. If you score \(>60\%\) on quizzes, you will receive full participation credit. Your lowest two quizzes will also be dropped.

Where to find help

Office hours

Many questions are most effectively answered in-person, so office hours are a valuable resource. Please make use of them. A list of instructor and TA office hours can be found on the course website.

Slack

Outside of class and office hours, any general questions about course content or assignments should be posted on Slack. The instructors and TAs will monitor Slack and reply to your public or private messages. Also, feel free to answer posted questions and ask follow-up questions.

Policies

Academic integrity

You should be familiar with Duke’s community standard: https://studentaffairs.duke.edu/conduct/about-us/duke-community-standard

By enrolling in this course, you commit to upholding Duke’s community standard reproduced as follows:

I will not lie, cheat, or steal in my academic endeavors;
I will conduct myself honorably in all my endeavors; and
I will act if the Standard is compromised.

Any violations in academic integrity standards as outlined in the Duke Community Standard and those specific to this course will automatically result in a 0 for the assignment and will be reported to the Office of Student Conduct for further action.

Please abide by the following as you work on assignments in this course:

You may discuss lab assignments with other students; however, you may not directly share (or copy) code or write up with other students. For team assignments, you may collaborate freely within your team. You may discuss the assignment with other teams; however, you may not directly share (or copy) code or write up with another team. Unauthorized sharing (or copying) of the code or write up will be considered a violation for all students involved.
You may not discuss or otherwise work with others on the exams. Unauthorized collaboration or using unauthorized materials will be considered a violation for all students involved. More details will be given closer to the exam date.
Reusing code: Unless explicitly stated otherwise, you may make use of online resources (e.g. Stack- Overflow) for coding examples on assignments. If you directly use code from an outside source (or use it as inspiration), you must explicitly cite where you obtained the code. Any recycled code that is discovered and is not explicitly cited will be treated as plagiarism.

Team work policy

The final project and several labs will be completed in teams. All group members are expected to participate equally. Commit history may be used to give individual team members different grades. Your grade may differ from the rest of your group.

Errors in grading

Errors in grading must be brought to the attention of the TA or instructor during office hours within 1 week of receiving the grade.

Late work

Late work may be submitted with 48 hours of the assignment deadline. Late work submitted within 24 hours (even 1 minute late) will receive a 5% late penalty. Late work submitted between 24 to 48 hours of the deadline will receive a 10% late penalty. Work submitted after 48 hours will not be accepted. Exams cannot be turned in late and can only be excused under exceptional circumstances. The Duke policy for illness requires a short-term illness report or a letter from the Dean; except in emergencies, all other absenteeism must be approved in advance (e.g., an athlete who must miss class may be excused by prior arrangement for specific days). For emergencies, email notification is needed at the first reasonable time.
