AIMS AND CONTENT

AIMS AND LEARNING OUTCOMES

The teaching aims to provide students the fundamental knowledge for the organization and study of ecological data, the structuring of an experimental design in ecology and the choice and use of the main univariate and multivariate analysis techniques. Students will also be introduced to the use of the open source software R for the creation of graphs, data exploration and statistical analysis of univariate and multivariate data.

TEACHING METHODS

The teaching consists of lectures and applied lessons (in the computer room) where students will learn to apply data analysis techniques using the R software.

Lectures are delivered through multimedia presentations, video, quiz and individual or team practice exercises, which can be performed both in the classroom or on-line.

Please refer to AulaWeb application specific for the teaching for potential updates due to changes in the health and epidemiological situation.

QUANTITATIVE ECOLOGY

EXAMS

EXAM DESCRIPTION

The exam consists of an oral test concerning the topics covered in the course. The exam is passed if the student has obtained a grade greater than or equal to 18/30.

Five appeals will be available in the summer session (June, July, September) and 2 calls in the winter session (January-February).

Please refer to AulaWeb application specific for the teaching for potential updates due to changes in the health and epidemiological situation.

ASSESSMENT METHODS

Details on how to prepare for the exam and the degree of detail required for each topic will be provided during the lessons.

The exam will verify the actual acquisition of knowledge, which the student will have to be able to connect and integrate. The ability to synthesize and recognize the main aspects of the topic will be evaluated and the ability to expose the arguments clearly and with correct terminology will also be considered.
