Data Science Concepts / Data Science Tools

Note for students of Master program: Data Science for Society and Business (online)

This is NOT the official syllabus of the Master program: Data Science for Society and Business (online)!

You have modules with the same names in your program and also the instructors are the same, but the Modules are different! Look it up in your DSSB (online) handbook. Most importantly, your course will give you more ECTS, so do NOT count on the passing and grading requirements communicated here, they are not valid for you!

You are free to also use the material provided here, but look in the handbook and the learning platform for the official information!

Developing Syllabus

This syllabus may change during the course of the semester with some additions and clarifications.
All substantial changes will marked here with date.

Update Nov 10, 2024: Specification of module passing requirement for Data Science Tools! (See below.)

5 Format and Workload

Concepts: Lectures, sometimes with aspects of Tutorials (35 hours in presence, total expected workload 125 hours)
Tools: Tutorials, sometimes with aspects of Lectures (35 hours in presence, total expected workload 125 hours)

Besides homework, both modules require a decent amount of self-study.
Workload homework and self-study is expect to be 90/125 = 72% of the total workload.

Homework assignments are given along the concepts treated in Concepts to be solved with the tools treated in Tools.

6 Intended Learning Outcomes

The module descriptions can be found in the DSSB Handbook

6.1 From the handbook

By the end of the Concepts module, you will be able to:

1. understand and use the mathematical foundations of statistical learning algorithms
2. explain and classify data science problems
3. explain and classify data-driven approaches
4. understand the application of data science techniques to typical situations and tasks in business and societal research, including the search, retrieval, preparation, and statistical analysis of data
5. interpret complexity analysis and performance evaluation of data science problems and algorithms

By the end of the Tools module, you will be able to:

1. explain basic concepts of imperative and object-oriented programming
2. write, test, and debug programs
3. perform data handling and data manipulation tasks in R and Python
4. apply your knowledge to implement own functions in R and Python
5. effectively use core packages and libraries of R and Python for data analysis
6. know about the typical applications of R and Python in data science
7. implement and apply advanced data mining methods with appropriate tools
8. perform a full cycle of data analysis

6.2 Main Learning Goal

Our main goal to help you build a good basis for your more and more independent work in the whole study program. That means you can

• learn core concepts in data science on your own, for example
  • concepts to explore data (import, wrangle, visualize)
  • learn and explore mathematics and statistics through the data science lens
  • learn concepts to model and draw conclusions from data (model, infer, predict)
• create and maintain a digital working environment on your computer to do data science
• learn to program in the data science languages R and python, and become able to learn new skills in these independently
• do a data science project of your own interest

7 Examination and Assessment

For students of DSSB (online)

These information does NOT apply for you, check your handbook.

7.1 Concepts Module

Assessment Type: Written Examination
Duration: 120 min
Weight: 100%
Scope: All intended learning outcomes of the module.
Completion: to pass this module, the examination has to be passed with at least 45%

An exam will take place after all lectures in December. The date will be published by the university adminstration later.

There are no additional achievements necessary and there are no bonus options.

7.2 Tools Module

Module achievement: 50% of the assignments correctly solved
Programming and analysis assignments will appear step by step during the courses.
To pass the module you have to solve half of them by the end of the semester.

Assessment Type: Project Report
Length: 4000 - 5000 words (This is a guideline, not a strict rule! Content counts, we will not count words.)
Weight: 100%
Scope: All intended learning outcomes of the module.

More information of project formats and grading rubric: Final Projects

Bonus option: Students receive 0.33 points grade improvements on their project grade on the numerical grade as specified in the Grading Table when all assignments are solved by the end of the semester. (Note, the bonus is not necessary to reach the best grade in the module.)

All assignments and the final project must be delivered in personalized repositories in the GitHub organization.

Update Nov 10, 2024:

Homework Specification for Passing and Bonus

By the end of the semester, all Homework repositories will be assessed as

• “Just Passed” when half of the tasks are solved meaningfully,
• “Passed” when almost all tasks are solved (some shortcomings are acceptable),
• “Bonus” when the solutions are great, or
• “Fail” when none of this has been achieved.

To pass the module (50% Module Achievement such that the student can be assessed on the final project) a student needs to have all Homework Projects at least as “Just Passed” (no “Fail”). However, a “Fail” in one Homework can be compensated by a another Homework being “Passed” or “Bonus”.

To receive the bonus for the module assessments a student needs to have more than half of the Homework Projects at “Bonus” and all others at “Passed” (no “Fail” or “Just Passed”).

8 Module Policies

There are no formal requirement about attendance and active participation. However, we rely on your engagement in a many-facted way including:

• Preparation (looking at readings and material before and after class, being informed about syllabus and course material)
• Focus (avoid distraction during in class and self-learning activities)
• Presence (listening and responding during group activities)
• Asking questions (in class, out of class, online, offline, when you get stuck conclude by writing a question)
• Specificity (being as specific as possible when describing your problem or question)
• Synthesizing (making connections between concepts from reading and discussion)
• Persistence (you don’t need to understand everything immediately, but stay engaged, try again, confusion shows that you pay attention)

9 Academic Integrity

All involved parties (professors and lecturers, instructors and students) are expected to abide by the word and spirit of the “Code of Academic Integrity”. Violations of the Code might be brought to the attention of the Academic Integrity Committee.

10 Artifical Intelligence (AI) Use Policy

This policy covers any generative AI tool, such as ChatGPT, Elicit, Gemini, Claude, CoPilot, etc. This includes text, code, slides, artwork/graphics/video/audio and other products.

We instructors encourage exploring AI tools for these purposes:

• Learning by dialog with a chatbot. AI chatbots can be helpful to explain you concepts on your desired level and get a feeling about how topics are treated. You can ask for an easier or more detailed explanation or focus on certain aspects. Note: The capabilities are limited and you likely receive also false information! An AI chat can be a good entry point to learn about a specific topic but the more specific it gets the more likely it is that AI will start to deliver useless or wrong answers. Using chatbots should remain a small part of your learning process. Rule of thumb: Spend not more than 25% of the learning time with chatting with AI. There is no way around reading textbooks, reading software documentation, learning and understanding concepts, searching for help online, asking instructors or fellow students.
• Have code snippets written. Tools like GitHub Copilot can be a great help in coding! Try them, many coders do it. Maybe the GitHub Copilot is stil free to use for students and teachers who join GitHub Education), they can be integrated in your programming IDE like RStudio and VSCode. Copilots can speed up writing. However, they may deliver bad code. There is no way around understanding yourself what code is doing! Do not spend endless hours asking for new code with new prompts, spend time understanding a language and the functions and objects you are using! AI chatbots and Copilots can also help you to understand code. Copilots can be a great help to get a skeleton of code and an idea how your solution might look. They rarely deliver the complete code. Expect that the code does not work, expect that the code seems to works but the results are wrong! You are 100% accountable for the code you produce, with or without the help of a copilot! When a task in a Homework project can be well solved by Copilot we are happy if you drop us a note, same when it is totally off, it is interesting to explore what AI can do well and what not.
• Have a draft text snippet written. Formulating and describing research questions, describing data, documenting code, interpreting results, and deriving conclusion form the results is an essential part of data science. Chatbots are good in writing text which appears well readable. You can use this to inspire you and to polish and improve your texts. However, you are 100% accountable for the text you deliver. You are expected to know what your text is about and to be able to answer questions about what your text means! With text generated purely by chatbots, it is often evident for us that students do not understand. We consider such cases worse than incomplete but sensible self-written text. Text written by chatbots is often very generic and not specific. In general, we value more specific text higher than generic text. Long generic text is considered worse than a shorter more specific text.

Note: Philosophical and legal questions around the training and use of chatbots and code copilots are controversially contested and re-examined constantly! We encourage to engage with such questions and become aware of arguments and debates.

If any part of this AI policy is confusing or uncertain, please reach out to us for a conversation before submitting your work.
