Teaching results

Knowledge - Graduates of the course will learn to modify data into a form suitable for exploratory data analysis and visualisation. They will learn the basic techniques of graphical data representation and learn to use the principles of data presentation. At the same time, the most common errors associated with the visual presentation of data are identified.
Skills - By completing the course, the student will improve analytical and presentation skills through data visualization.
Competences - Graduates of the course will be able to process data into a suitable for analysis and identify a suitable visualization technique for convincing presentation of trends, structures or. extreme values in data. These competencies will serve for better decision-making at the level of companies as well as in public administration.

Indicative content

The course is focused on practical skills in the field of data analysis through their visualization and effective communication of results to the public. The course is organized in three parts. In the first part, students will learn to modify data into a form suitable for analysis (eg data organization, data cleaning, data pivoting). In the second part, they will learn the principles and acquire practical skills of visualizing data distribution (data distribution through histogram, box plot graph, maps) and relationships between data (eg scatter plot, scatter plot matrix, bubble chart, parallel coordinate plot). All skills will be explained on practical examples in specialized software. In the last part, students will learn the principles of graphic presentation and how to avoid the common mistakes.
