Descriptive Methods of Data Mining


Data Mining uses interdisciplinary techniques, such as statistics, data visualization, database systems, and machine learning to identify original, useful, and understandable patterns in data.
This course will familiarize students with Data Mining applications and Data Mining projects' lifecycle. Students will learn techniques for understanding and preparing data before building descriptive models, such as clustering or association rules (e.g., market basket analysis).

Teaching language

Portuguese. If there are Erasmus students, classes will be taught in English


Familiarity with the main theme of the course is not required. But it is highly recommended that the students have knowledge of Inferential Statistics as well as good skills as a computer user.

Students without previous training or experience with Python should complete the two following Datacamp online courses before the third week of this course (first practical class):  Introduction to Python and Intermediate Python. Students who wish could also complete, optionally, the course Data manipulation with pandas. The instructor will provide information on how to have free access to the Datacamp platform.


Teaching method

The course is based on theoretical and practical classes. Several teaching strategies are applied, including slides presentation, step-by-step instructions on approaching practical examples, and questions and answers. The practical component is oriented towards exploring the tools introduced to students (Microsoft Excel and Python) and the development of the project.

Applications used: Microsoft Excel, Python, Jupyter notebook, Microsoft visual studio code.

Evaluation method

Due to the application-based design of the course, evaluation is continuous and applies to both the theory and practical components. There is no ¿one only exam¿ with a single weight of 100%.

All evaluation grades are on a scale of 0-20.

  • Python Quiz:
    • Individual - with materials consultation
    • The minimum grade is 8.0
    • 10% weight
  • Group project:
    • The minimum grade is 8.0
    • 40% weight
  • Exam:
    • Individual - with materials consultation
    • The minimum grade is 8.0
    • 1st season or 2nd season: 50% weight

All submissions should be made via Moodle. Submissions after the deadline will be rejected.
