The lecture evaluation has been opened: TISS

All information about the lecture (Zoom links, slides, etc) can be found on TUWEL.
Please post your questions about the lecture in the TUWEL forum.


The VU Visual Data Science will discuss how techniques from visualisation and visual analytics can be applied to data science. The lecture will start with a theoretical introduction to different concepts of visualisation and visual analytics (lecture 1-5). The second part of the lecture (lecture 6-10) will deal with the practical application of Visual Data Science, namely the selection of charts, trust in visualisations, and applications and libraries. An important part of this VU will be the lab part, where students will have to try out different visualisation techniques and applications to achieve certain tasks.

The lab part of the VU consists of two parts. Lab organisation and submissions are done via TUWEL.

Part 1

In the first part students will study the relations between statistical analysis and visual data analysis. A multivariate dataset is provided, and three tasks have to be solved, using statistical methods and visual analysis. A written report has to be submitted until November 18th, 2020.

Part 2

In this second lab part students will analyse a dataset and create a dashboard for data analysis and presentation. A written report has to be submitted until January 15th, 2021. On January 20/21/27/28, 2021 students will present their solutions in online sessions (register for a slot in TUWEL).

Exam questions

Between January 22nd, 2021 and February 12th, 2021 exam questions about the theoretical content of the lecture will have to be answered in TUWEL.


The following points can be achieved in the lecture:

Lab part 1 (report) 20 points
Lab part 2 (report) 30 points
Lab part 2 (presentation) 30 points
Exam questions 20 points

The points define the final grade:

Sehr Gut (1) > 85 points
Gut (2) > 75 points
Befriedigend (3) > 62 points
Genügend (4) > 50 points
Nicht Genügend (5) <= 50 points
