Learning objectives
For most learning objectives the use of R is implied.
  • Be able to load, process, and transform data stemming from different sources and structured in different ways. • Summarize data and apply visualization techniques to explore and present data.
  • Summarize data and apply visualization techniques to explore and present data.
  • Identify, apply and compare suitable machine learning techniques to business and social data.
  • Effectively communicate your results, model assumptions, and share well documented and formatted code, following best practices.
  • Formulate data driven conclusions for social and business applications, while incorporating considerations related to uncertainty and causality.
Course prerequisites
Note on software use and prerequisites:
Students are expected to spend a substantial amount of time working with software, i.e. developing their coding skills. The course software will be R, but no prior knowledge of R is expected. The first part of the course will introduce the software step-by-step through various applications.

As this is an introductory course, there are no formal prerequisites. However, any previous statistics, quantitative research methods, or potential computer science/programming course participation will be an advantage.
Prerequisites for registering for the exam (activities during the teaching period)
Number of compulsory activities which must be approved (see section 13 of the Programme Regulations): 1
Compulsory home assignments
Number of compulsory activities which must be approved: 1
Compulsory home assignments

There will be a total of two compulsory activities consisting of written home exercises. One out of two activities must be approved to qualify for the exam. Feedback on the assignments will be offered through video supporting material and/or feedback meeting.

No further attempts to pass the mandatory activities will be provided before the ordinary exam. If a student has not had the required number of activities approved, the student will not be able to attend the ordinary exam. Should the student fail at the ordinary exam then no further activities are required to qualify for the retake.

If the student fails to qualify for the ordinary exam:
In order to qualify for an extra mandatory activity before the retake the student must have (either) 1) attempted both activities without succeeding in having them all approved; and/or 2) provided relevant documentation of illness or other extenuating circumstances.

In such cases s/he must, before the retake submit a paper covering the substance of the required number of mandatory activities. Specific requirements are provided by the course coordinator. When the paper is approved by the course coordinator, the student may be registered for the retake.

Description of the exam procedure

Students will be required to carry out data analysis relying on the tools discussed in the course
Course content, structure and pedagogical approach

Data science—bridging statistics, computer science, and substantive area expertise, has become an integral part of decision-making since the availability and diversity of data sources have recently increased at an unprecedented pace. The course provides students with applied introductory knowledge about working with data to understand and inform various business and social decisions. Upon completing the course, the students should be able to understand the techniques introduced in the course and apply them to new data and specific problems. The course content covers two broader areas:

 

  1. Working with data: data wrangling, transformations, summary, text-as-data, & visualization.
  2. Machine learning techniques and principles : such as supervised vs. unsupervised learning, regression, classification, regularization, uncertainty, etc.

 

The teaching format is “particular general particular”. We will introduce a particular question or application, discuss how such a question is handled in general by reviewing core concepts from the literature, and we then return to the particular application by focusing implementation and extensions. Throughout the course we will follow an applied, hands-on approach, also always working on implementation and coding. Hence, students will spend a substantial amount of time working with software, including compulsory activities and final examination. The course software will be R. All activities will be based on data (or type of data) often used in private and public organizations.

 
Description of the teaching methods
Teaching will be carried out as a mix of lectures, exercises, and forum activities, allowing for coding together and code review.
Feedback during the teaching period
Feedback will be offered for the compulsory activities during the course through solution videos (1) and the review of most common recommendations for future work in a feedback meeting (2). Feedback regarding specific inquiries will be given during ‘office hours’ offered by full-time staff members, although these can never be a substitute for participation in the regular teaching activities. Generally, we encourage you to ask questions or make comments on the online forums used and during our sessions.

Student workload
Lectures, exercises and workshops 51 hours
Exam 36 hours
Course preparation. Includes: readings for lectures and exercises work on activities (homeworks) 132 hours
