All the materials including lecture notes, homework, solutions, links to videos and web
resources, will be available in our moodle site.

### Teaching method

Students are welcome to bring their own devices (e.g IPhones, Smartphones, IPads, Notebooks) to class as this is a BYOD course: you will need to be connected during classes (to moodle and adequate sources of information in real time).

The course will be driven through practical exercises. Students will learn solving exercises.

Classes will be divided into individual and team building knowledge. Students will be graded in every class for their learning effort, by solving individual and team quizzes.

### Evaluation method

• Quizzes – 30%
Final exam (minimum 8 out of 20) – 70%

• Final grade = Max (Final Exam; Weighted Grade) although roster: Pass/Fail

• The students will need to build their own form (with no solved exercises) to be used during the classes and exam. The allowed and required material for the exam is a pen, a calculator, the student’s form and the statistical tables (Standard Normal and t-Student). Any additional
sources of information in addition to those previously mentioned are not allowed.
