Annotation -
Introductory course to Data Science with applications in the R programming environment. Special focus is put on understanding of basic practical programming in R, covering model evaluation, memorization methods, advanced regression techniques, and training variance reduction. The Data Science with R I course will be followed by Data Science with R II covering clustering, text mining, support vector machines, neural networks, and networks.

Aim of the course -

The main aim of the set of courses (Data Science with R I + II) is to train students to be able to properly analyze specific datasets with methods outside of standard econometric framework using the R programming environment.

Course assessment methods and requirements for successful completion, grading scheme -

There are 4 components to the final score and grade:

  • 3 Core Assessments in DataCamp (3*5 = 15 points)
  • 3 Courses in DataCamp (3*10 = 30 points)
  • 1 Topical Assessments in DataCamp (25 points)
  • 1 Research Report (30 points)

Use this LINK to register to DataCamp, fill in the profile (properly, use your name, it will be used to track fulfillment of assignments), and complete your assignments there. If you do not have a @fsv.cuni.cz/@cuni.cz/@m365.cuni.cz email, let me know, I will send you an invite.

Core Assessments (upload a printscreen of your finished assessments to the Study Roster, make sure you name is visible in the printscreen):

  • R Programming (5 points) - by 26 October 2025 CET
  • Exploratory Analysis Theory (5 points) - by 26 October 2025 CET
  • Analytic Fundamentals (5 points) - by 26 October 2025 CET
  • You need to get at least 120 score to obtain 5 points for each of these three Core Assessments (MANDATORY).
  • You can re-take the assessments twice a week up till the deadline. Remember that the last one counts (not necessarily the best one).

Courses (upload certificates or screenshots of completion to the Study Roster, separately for the completed courses):

  • Supervised Learning in R: Classification (10 points) - by 30 November 2025 CET
  • Supervised Learning in R: Regression (10 points) - by 14 December 2025 CET
  • Machine Learning with Tree-Based Models in R  (10 points) - by 28 December 2025 CET

Topical Assessment (upload a printscreen of your finished assessments to the Study Roster, make sure you name is visible in the printscreen):

  • Machine Learning Fundamentals in R (25 points) - by 25 January 2026 CET
  • To get the score, use the DataCamp score x and fit it to (x-60)/80*100%
  • At least 50%, i.e. at least 12.5 points, is a necessary (not a sufficient) condition for passing the course.
  • You can re-take the assessments twice a week during the whole semester (up till the deadline). Remember that the last one counts (not necessarily the best one).

Research Report (upload a zip file including the report, R code, and dataset, to the Study Roster):

  • Teams of up to 4 students.
  • Up to 10 pages (including everything but the code and data which will form separate attachments).
  • Submit by 1 February 2026 CET

Grading scale follows the faculty regulations:

  • A: 90+
  • B: 80-90
  • C: 70-80
  • D: 60-70
  • E: 50-60
  • F: below 50
