Requirements to the exam -

There are 3 components to the final score and grade:

2 tracks in DataCamp (40 points)
3 assessments in DataCamp (30 points)
1 research report (30 points) (you can use this shared table to set up teams)

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/@.365.cuni.cz email, let me know, I will send you an invite.

Tracks (upload certificates of completion to the Study Roster, separately for the completed tracks):

Track 1: Skill Track "R Programming Fundamentals" (15 points) - by 10 November 2024 CEST
Track 2: Career Track "Data Analyst with R" (25 points) - by 26 January 2025 CET

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

Assessment 1: Data Manipulation with R (10 points) - by 10 November 2024 CEST
Assessment 2: Statistics Fundamental in R (10 points) - by 1 December 2024 CET
Assessment 3: R Programming (10 points) - by 22 December 2024 CET
Scoring:

To get the score, use the DataCamp score x and fit it to (x-60)/80*100%
At least 50%, i.e. at least 5 points, from each assessment is a necessary (not a sufficient) condition for passing the Data Analysis in R course.
You can re-take the assessments twice a week during the whole semester. 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 8 pages (including everything but the code and data which will form separate attachments).
Submit by 2 February 2025 CET.

Grading scale follows the faculty regulations:

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