Course learning objectives
- Learn to explore, visualize, and analyze data in a reproducible and shareable manner
- Gain experience in data wrangling and munging, exploratory data analysis, predictive modeling, and data visualization
- Work on problems and case studies inspired by and based on real-world questions and data
- Learn to effectively communicate results through written assignments and a final project presentation
Activities and assessments
The following activities and assessments will help you successfully achieve the
course learning objectives. By experiencing the course content in different
ways, you will not only gain a better understanding of data science, but you
will also get experiences that can guide you as you apply what you've learned
in future academic and professional projects.
In homework, you will apply what you've learned during lecture and lab to complete data analysis tasks. You may discuss homework assignments with other students; however, homework should be completed and submitted individually. Homework must be typed up using R Markdown and submitted in the appropriate GitHub repository.
The lowest homework grade will be dropped at the end of the semester.
In labs, you will apply the concepts discussed in lecture to various data analysis scenarios, with a focus on the computation. You will work on lab assignments individually and in teams; all team members are expected to contribute equally to the completion of each assignment. You are expected to use the assigned Git repository on the course's GitHub page as as the central platform for collaboration. Commits to this repository will be used as a metric of each team member's relative contribution for each lab. You will also be asked to evaluate your team members' performance periodically during the semester.
The lowest lab grade will be dropped at the end of the semester.
The exams are an opportunity to assess the knowledge and skills you’ve learned.
Both exams will be take-home assignments that you are expected to complete
individually. Each exam will include small analysis and computational tasks
related to the content discussed in lectures, application exercises, homework
assignments, labs, and assigned readings. More details about the content and
structure of the exams will be discussed during the semester.
The purpose of the project is to apply what you’ve learned throughout the
semester to analyze an interesting data-based research question. The project
will be completed in teams, and each team will present their results during the
final exam period, Wednesday, April 29, 2:00pm - 5:00pm.
You must complete the final project and present your work in class to pass the course.
Participation and application exercises
Application exercises give you an opportunity to practice using the statistical
concepts and/or code discussed in lecture on short data analyses.
They will typically be started during class and may be assigned to be completed
by the next class meeting. In general, these assignments are shorter than
homework assignments and will be completed in teams.
To construct functional and diverse teams, you will be asked to complete a
short survey to gauge your previous exposure to programming topics. After
completing the survey, you will be assigned to teams of 3-4 students; these
teams will stay consistent throughout the semester
(barring extraordinary circumstances).
You will work in these teams during class, on application exercises, on labs,
and on the final project.
The final grade will be calculated as follows:
|Participation & Application Exercises||5%|
Class attendance in lecture and lab is a firm expectation; frequent absences or tardiness will be considered a legitimate cause for grade reduction.
If you have a cumulative numerical average of 90 - 100, you are guaranteed at least an A-, 80 - 89 at least a B-, 70 - 79 at least a C-, and so on.
In this course, we will strive to create a learning environment that is
welcoming to all students and that is in alignment with Duke’s Commitment to Diversity and Inclusion.
If there is any aspect of the class that is not welcoming or accessible to you,
please let me know immediately. Additionally, if you are experiencing something
outside of class that is affecting your performance in the course, please feel
free to talk with me and/or your academic dean.

Where to find help
- If you have a question during lecture or lab, feel free to ask it! There are likely other students with the same question, so by asking you will create a learning opportunity for everyone.
- The teaching team is here to help you be successful in the course. You are encouraged to attend any of the office hours posted on the home page to ask questions as you study the course content and work through assignments. A lot of questions are most effectively answered in-person, so office hours are a valuable resource. Please use them!
- Outside of class and office hours, any general questions about course content or assignments should be posted on Piazza since there are likely other students with the same questions. The questions you post will be visible to the entire class, so please email the instructor directly with any specific questions about grades or personal matters.
Sometimes you may need help with the class that is beyond what can be provided by the teaching team. In that instance, I encourage you to visit the Academic Resource Center.
The Academic Resource Center (ARC) offers free services
to all students during their undergraduate careers at Duke. Services include
Learning Consultations, Peer Tutoring and Study Groups, ADHD/LD Coaching,
Outreach Workshops, and more. Because learning is a process unique to every
individual, they work with each student to discover and develop their own
academic strategy for success at Duke. Contact the ARC to schedule an
appointment. Undergraduates in any year, studying any discipline can benefit!

Where to find course materials
All assignments and course materials may be found on the course website and GitHub page. There is also an up-to-date course schedule where you can find the lecture notes discussed in each class meeting, assignment deadlines, and reading assignments to help you prepare for each class.
Announcements may also be sent to the class by email, so please check your
Students who miss a class due to a scheduled varsity trip, religious holiday, or short-term illness should fill out an online NOVAP, Religious Observance Notification, or Incapacitation Form, respectively. These excused absences do not excuse you from assigned homework. It will still be your responsibility to submit relevant assignments in accordance with the deadline.
If you have a personal or family emergency or health condition that affects your ability to participate in class, you should contact your academic dean's office. More information about this procedure may be found on the Personal Emergencies page or provided by your academic dean.
Exam dates cannot be changed and no make-up exams will be given. If you must miss an exam, your absence must be officially excused before the exam due date. If your absence is excused, the missing exam grade will be imputed at the end of the semester based on your performance on other relevant course assignments.
The final project presentations will be during the university scheduled exam
period, Wednesday, April 29, 2:00pm - 5:00pm.
You must complete the final project and present your work during the exam period in order to pass the course.
Homework or lab assignments submitted late but within 24 hours of the deadline may be accepted with a 20% penalty. Homework or lab assignments submitted any later will not be accepted.
Late work will not be accepted for the exams or the final project.
By enrolling in this course, you have agreed to abide by and uphold the provisions of the Duke Community Standard as well as the policies specific to this course. Any violations will automatically result in a grade of 0 on the assignment and will be reported to Office of Student Conduct for further action.
- 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 dates.
- Reusing code: Unless explicitly stated otherwise, you may make use of online resources (e.g. StackOverflow) 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.
On individual assignments, you may not directly share code or write up with
other students. On team assignments, you may not directly share code or write
up with another team. Unauthorized sharing of the code or write up will be
considered a violation for all students involved.
Regrade requests should be submitted through the regrade request form on Gradescope. Requests for a regrade must be made within 48 hours of when the assignment is returned. Due to the time consuming nature of regrades, requests submitted later will not be regraded. Requests will only be honored if there is an error in the grade calculation or a correct answer was mistakenly marked as incorrect. Regrade requests made on the basis of grading being too harsh will not be recognized. Please note that by submitting a regrade request, your entire assignment may be regraded and you may potentially lose points. Therefore, you should attend office hours to ask a member of the teaching team about your grading feedback before submitting a regrade request.
No grades will be changed after the final project presentations.
Grades can only be changed by the instructor. Teaching Assistants cannot
change grades on returned assignments.
