Admission requirements:

This course is an (extracurricular) Honours Class: an elective course within the Honours College programme. Third year students who don’t participate in the Honours College, have the opportunity to apply for a Bachelor Honours Class. Students will be selected based on i.a. their motivation and average grade.

Key words:

Skills: Research, presenting, academic writing and reviewing

Topics: Data Science

Disciplines: Data science, Life Sciences, Social Sciences


Data Science deals with handling, processing, analyzing, interpreting, and extracting knowledge from data, ultimately to derive optimal decisions. Often, the term is associated with the concept of big data, i.e., data that is characterized by large volume, high velocity of generation, and data variety, meaning many different types of information.

Today, data science is of paramount importance in just about any domain, ranging from the life sciences, including e.g. health and biosciences, to banking, sports, insurances, retail, and heavy industries.

The possibilities for generating new insights and decisions based on data are considerable. This Honours Class first introduces students to some of the fundamental concepts of Data Science and then continues with overviews of specific application domains.

Course objectives:

Upon successful completion of this course, students:

  • have a general overview of the possibilities in the field of data science;

  • have knowledge of different types of data;

  • are able to understand and perform basic data analysis tasks;

  • have basic knowledge of some of the tools used in data science;

  • have developed skills for several tools for analyzing data;

  • have experience with performing basic analyses for real-world applications.
