Both local start-ups such as "Gurkerl" and multinational companies such as "Amazon" have invested heavily in their data science departments. Experiments and machine learning algorithms are running around the clock to gain insights from huge amounts of data. Nevertheless, the insights gained need to be translated into actionable business decisions. This can lead to ineffective communication when data scientists and business leaders use divergent language.

This course offers students the opportunity to bridge the gap between data science and business decisions and become "data translators". The course offers insights into the interaction of data, narratives and visualizations, and their underlying neuroscientific concepts. Students will learn how to communicate data effectively when the intended audience is not familiar with statistical and data science jargon. Specifically, this will be done via visualizations. Students will be introduced to the learning content both theoretically and practically.

This course is divided in three parts:

1. Theory and practice of storytelling;
2. Causal inference;
3. After a brief introduction to the neuroscience of perception, we will focus on its application to the theory and practice of visualization.

This course uses the R programming language to interpret and present data. No prior knowledge of R is required.

Methods, principles and theories of data interpretation and visualization as well as communication of data-based analyses and their application in a business setting.

The objectives of the course are:

• To become a translator between data scientists and business leaders;
• To learn how to interpret and communicate causality within a business setting;
• To learn how to effectively communicate data-based analyses using appropriate, neurally-effective visualization and presentation techniques;
• To learn how to analyze and interpret data using the R programming language.

Attendance is compulsory in all course units. To pass the course, you must be present for at least 80% of the time in the units. If you are unable to attend a unit, please inform the course instructor before the unit. The content covered in a missed unit must be made up independently.

The course is taught through a combination of interactive sessions, class discussions and student presentations. Theories will be applied to real-world examples and implemented by students in a mini-project at the end. The goal is to create an open learning environment that encourages trial-and-error, discussion, and further development of practical skills for data-driven businesses. The focus of the course is on (the neural representation of) data visualization and the tools required to create interpretable and engaging diagrams for different audiences.

To be prepared for the lectures, you will need to work through the assigned material for the week and be prepared to answer questions about it. The sessions themselves are designed to (1) identify and apply theoretical concepts and (2) clarify unclear points that need further discussion.

The grading is made up as follows:

• Group presentations (40%)
• Final exam (30%)
• Participation in discussions based on the study material (written or oral; 10%)
• Homework (20%)

The grading scheme is defined as follows

< 60% not sufficient (5)

60% to 69.99% sufficient (4)

70% to 79.99% satisfactory (3)

80% to 89.99% good (2)

>= 90% very good (1)
