CSci 39542: Introduction to Data Science
Department of Computer Science
Hunter College, City University of New York
Spring 2022

Description: 3 hours, 3 credits: This topics course focuses on computational methods and statistical techniques to analyze data and make inferences. Topics include data collection and cleaning, exploratory data analysis and visualization, and statistical inference and prediction. Students will acquire a working knowledge of data science through hands-on projects with real-world data. Basic proficiency in statistics and Python programming is assumed, as well as experience with abstract data structures.
Prerequisites: CSci 127, Stat 213, and one of: CSci 133 or CSci 235.
Instructors: Dr. Katherine St. John, professor (office hours) and Susan Sun, Tech-in-Residence (TiR) fellow.
Meetings: Mondays, Thursdays, 2:45-4pm, in-person.
Course Email: datasci@hunter.cuny.edu.

Grading Policy

Course Format: This course is taught in an in-person format:

• Synchronous in-person lectures are Mondays and Thursdays, 2:45-4pm,
• Assessments (as part of lecture or due 24 hours after lecture, depending on assessment),
• Individual programming assignments and cumulative project, and
• A two-part final examination given during the last class meeting (coding exam) and the time slot assigned by the registrar (written exam).

Expectations: Completing homework is an essential part of the learning experience. Students are expected to learn both the material covered in class and the material in the textbook and other assigned reading.

Honor Code: You are encouraged to work together on the overall design of the programs and homework. However, for specific programs and homework assignments, all work must be your own. As a general rule, do your own typing. Submitting work of others, or not safeguarding your work from copying, are academic integrity violations. You are responsible for knowing and following Hunter College's Academic Integrity Policy:

Hunter College regards acts of academic dishonesty (e.g., plagiarism, cheating on examinations, obtaining unfair advantage, and falsification of records and official documents) as serious offenses against the values of intellectual honesty. The College is committed to enforcing the CUNY Policy on Academic Integrity and will pursue cases of academic dishonesty according to the Hunter College Academic Integrity Procedures.

All incidents of cheating will be reported to the Office of Student Conduct in the Vice President for Student Affairs and Dean of Students office.

Lecture Participation: Participation in lecture is measured by collected classwork. If you miss or do poorly on a classwork, your grade on the written final exam will replace the missing or low grade.

Quizzes: Every week, there will be an quiz on the lecture notes, code demonstrations, classwork, and submitted programs. Quizzes are timed coding challenges, using the HackerRank platform:

• Each quiz is 30 minutes and can be taken within 24 hours after Thursday lecture. Once you start a quiz, it must be completed in one setting.
• All work must be your own and done in the IDE provided. Cutting-and-pasting code will raise plagiarism flags as will leaving the window. Incidents of plagiarism are reported to the Office of Student Conduct.
• Links to access the quizzes are available on Blackboard in the Quizzes submenu.
• There are no make-up quizzes. Instead, your score on the coding final exam will replace missing quiz grades (the coding final exam will also replace a quiz grade when you take the quiz but do better on the coding final exam).

Programming Assignments: Assignments are posted on the class website, usually two weeks before the due date. They reinforce concepts covered in lecture and lab and serve as building blocks for the classwork and the semester-long project.

• To receive full credit for a program, the program must perform correctly, must include comments, be written in good style, and be submitted via Gradescope.
• While you may consult and discuss with others, this is an individual assignment, and all code must be written and typed by you. All programs are run through similarity review and copied code is reported to the Office of Student Conduct.
• To encourage starting early on assignments, bonus points are available for submitting the programming assignments early (more details).
• No late homework is accepted. Instead, the top 10 weekly programming assignments are counted towards the final programming grade.

Project: A final project is optional for this course. The grade for the project is a combination of grades earned on the milestones (e.g. deadlines during the semester to keep the projects on track) and the overall submitted program. If you choose not to complete the project, your written final exam grade will replace its portion of the overall grade.

Final Exam: The final exam has two parts:

• Coding Exam given on the last day of class, Monday, 16 May, 2:45-4pm, in the style of the weekly course quizzes.
• Written Exam given during finals week on the day and time assigned by the registrar: Monday, 23 May, 1:45-3:45pm.

Both parts are required and are comprehensive, covering all the material of the course. Sample exam questions will available during the last weeks of the term.

Grades: The grading for the course will be based on:

• Participation: 10%.
• Programming Assignments: 15%.
• Quizzes: 15%.
• Optional Project: 20% (if you choose not to do the project, the final exam replaces the grade).
• Final Exam:
  • Coding Exam: 20%
  • Written Exam: 20% (or 40% if you choose not to do the optional project).

We understand that emergencies happen during the term, and as such, we

• Drop the lowest programming grades,
• Replace low or missing grades on the coding quizzes with your coding exam grade, and
• Replace low or missing classwork participation and project with the written exam grade.

See individual sections above for details. To respect your privacy, there is no need to provide documentation to take advantage of the dropping/replacing grades above. It is done automatically. If you are going to miss more than 2 weeks of class and associated work, contact us, so we can make arrangements for you to take the course in a future term.

Materials, Resources and Accommodating Disabilities

This is a zero cost course. All textbook materials are freely available to enrolled students.

Textbook & Readings: The following free on-line books are required for the course:

• UC Berkeley's Data Science 8 (DS 8): The Foundations of Data Science By Ani Adhikari and John DeNero.
