ENVIRONMENTAL DATA ANALYSIS

The course is one of the core educational activities of the Master's Degree Program in Environmental Sciences (Curriculum in Global Environmental Change). Quantitative data analysis is essential for Environmental Science
and knowing how to use it increases our understanding of environmental processes.
This module will provide an overview of commonly used statistical and graphical techniques for environmental data analysis.
Students will have the opportunity to design simple experiments, collect and analyze their own data, as well as analyze real data sets provided from different environmental research studies.
Moreover, we give an introduction into R, a freely available statistical and computational environment, which is widely used by scientists all over the world.
No prerequisite programming experience is required.

In this course, students will apply methods learned in a foundation course in Statistics to explore and answer key questions using relevant data from the Ecological and Environmental Sciences.
In so doing, students will confront the complexity of real-world data, and learn and practice essential tools for capturing, manipulating and sharing data.

Additional material (slides, notes) will be distributed by the teacher

The exam consist of a test directly on the computer, in which each student will analyze a data set proposed by the lecturer, and he/she will also have to answer some questions on the methodological part.
It is a closed book exam.

Student will be evaluated in terms of
- quality of his/her statistical analyses
- correct use of the technical terminology
- correct conclusions

This course is based on lectures, which will cover the major topics, emphasizing and discussing the important points.
Theoretical lectures will be complemented by exercise classes and lab sessions. The statistical software used in the course is R (www.r-project.org).
The personal participation is important, and it will help the student to learn more efficiently to read the assigned material to reinforce the lectures.
R scripts from various sources may be used to reinforce the material.

English

The attendance to each class (listening) and a genuine effort in doing the suggested exercises are two of the most important factors affecting the success in this course. Statistical analysis require both listening and doing.
