Anonymous statistical survey

Once two-thirds of the lessons have been completed, a statistical survey will be conducted to gather students’ opinions about the course in order to make it more effective. Reference sites:

Teaching methods

The course consists of 6 ECTS divided into two modules:

• Theory module, 4 ECTS
• Laboratory module, 2 ECTS

The lessons lasts 4 hours and include both a theoretical part (lecture and exercises) and a practical computer session using the students' computers, so as to become familiar with some of the methods underlying the subject.

Given the types of activities and teaching methods used, participation in this course requires all students to complete Modules 1 and 2 in e-learning mode via the following link:

Assessment methods

The assessment is aimed at verifying the acquisition of both the theoretical knowledge and the practical skills expected. The final grade reflects an evaluation of the content demonstrated during the exam.

The student must present a program for analyzing a dataset, agreed upon with the instructor, which will serve as the basis for discussing the topics covered in class.

The exam lasts 30–45 minutes.

Students who attend the course regularly may discuss with the instructor the possibility of including a midterm assessment.

As a guideline, the following evaluation criteria are provided:

• Failing

  • Incomplete knowledge of the subject
  • Lack of orientation within the topics
  • Inappropriate language

• Passing

  • Minimal knowledge of the subject
  • Analytical ability emerges only with the instructor’s help
  • Barely appropriate language

• Adequate

  • Good memorized knowledge of the subject
  • Fair argumentative ability
  • Correct language

• Excellent

  • Clear understanding and mastery of the subject
  • Excellent ability to elaborate and argue
  • Specific and appropriate language

Teaching tools

Blackboard (lectures and exercises), video projector, internet connection.

Computational laboratory practicals

The teaching materials presented during the lectures will be made available to students in electronic format on the official course website.

Students who require compensatory tools due to temporary or permanent disabilities, or specific learning disorders (SLD) may contact the appropriate University office well in advance:

• https://site.unibo.it/studenti-con-disabilita-e-dsa/en

The office will be responsible for proposing any necessary adjustments, which must be submitted at least 15 days before the exam date for the lecturer's approval. The lecturer will assess their appropriateness in relation to the learning objectives of the course.
