Recommended Prerequisites

Mathematics. Knowledge on probabilities and descriptive statistics.

Teaching Methods

This curricular unit includes both theoretical and practical classes. Teaching of the theoretical component is focus on the acquisition of knowledge and skills on different methods of data analysis and experimental design in biology. In the practical component, students come into contact with different software tools and will apply the acquired knowledge when taking decisions leading to problem solving and how to plan experiments.

Learning Outcomes

This course aims to provide students with the essentials of data processing and experimental design in biology, through understanding and applying different methods of data analysis and using different statistical software
