Meet data science

  • Data science is an exciting discipline that allows you to turn raw data into understanding, insight, and knowledge.

  • We’re going to learn to do this in a tidy way – more on that later!

  • This is a course on introduction to data science, with an emphasis on statistical thinking.

  • Each exam comprised of two parts:

    • In class: 75 minute in-class exam. Closed book, one sheet of notes (“cheat sheet”, no larger than 8 1/2 x 11, both sides, must be prepared by you) – 70% of the grade

    • Take home: The take home portion will follow from the in class exam and focus on the analysis of a dataset introduced in the take home exam – 30% of the grade

Caution

Exam dates cannot be changed and no make-up exams will be given. If you can’t take the exams on these dates, you should drop this class.

Project

  • Dataset of your choice, method of your choice

  • Teamwork

  • Presentation and write-up

  • Presentations in the last lab

  • Interim deadlines, peer review on content, peer evaluation for team contribution

  • Some lab sessions allocated to working on projects, doing peer review, getting feedback from TAs

Caution

Final presentation date cannot be changed. If you can’t present on that date, you should drop this class. You must complete the project to pass this class.

Teams

  • Assigned by me
  • Project
  • Peer evaluation during teamwork and after completion
  • Expectations and roles
    • Everyone is expected to contribute equal effort
    • Everyone is expected to understand all code turned in
    • Individual contribution evaluated by peer evaluation, commits, etc.

Grading

Category Percentage
Labs 35%
Project 20%
Exam 1 20%
Exam 2 20%
Application Exercises 5%

No specific points allocated to attendance, but attendance will be recorded periodically throughout the semester, and this information will be used as “extra credit” if you’re in between two grades and a minor bump would help.

See course syllabus for how the final letter grade will be determined.

Support

  • Attend office hours
  • Ask and answer questions on the discussion forum
  • Reserve email for questions on personal matters and/or grades
  • Read the course support page

Announcements

  • Posted on Canvas (Announcements tool) and sent via email, be sure to check both regularly
  • I’ll assume that you’ve read an announcement by the next “business” day
  • I’ll (try my best to) send a weekly update announcement each Friday, outlining the plan for the following week and reminding you what you need to do to prepare, practice, and perform

Diversity + inclusion

It is my intent that students from all diverse backgrounds and perspectives be well-served by this course, that students’ learning needs be addressed both in and out of class, and that the diversity that the students bring to this class be viewed as a resource, strength and benefit.

  • Please let me know your preferred name and pronouns on the Getting to know you survey.
  • If you feel like your performance in the class is being impacted by your experiences outside of class, please don’t hesitate to come and talk with me. I want to be a resource for you. If you prefer to speak with someone outside of the course, your advisors, and deans are excellent resources.
  • I (like many people) am still in the process of learning about diverse perspectives and identities. If something was said in class (by anyone) that made you feel uncomfortable, please talk to me about it.

Accessibility

  • The Student Disability Access Office (SDAO) is available to ensure that students are able to engage with their courses and related assignments.

  • I am committed to making all course materials accessible and I’m always learning how to do this better. If any course component is not accessible to you in any way, please don’t hesitate to let me know.

Course policies

Late work, waivers, regrades policy

  • We have policies!
  • Read about them on the course syllabus and refer back to them when you need it

Academic integrity

To uphold the Duke Community Standard:

  • 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.
