## Recommended Prerequisites

Biostatistics (mainly ANOVAs and Regression analysis).

## Teaching Methods

The course has a practical approach to the use of the different tools for data analysis. After the theoretical explanation of how each method works, students have to solve exercises in which to respond to the attached questions they have to use the different tools they have learned. In the final evaluation they will have to solve an exercise with several questions associated and where the application of different tools and the decisions taken in each analysis project must be clearly justified in order to evaluate whether students understood the modus operandi of these tools.

## Learning Outcomes

This course aims to provide students with advanced knowledge indispensable to the level of treatment of biological and environmental data in ecology, through the understanding and application of different methods of univariate and multivariate tools, promoting and encouraging their scientific skills and their critical abilities so they can understand, work and find appropriate solutions to the issues related to the integrated analysis of ecological and environmental data.

## Syllabus

1. Introduction to techniques or multivariate analysis: Terminology used; Brief description of existing techniques

2. Ordination techniques I: rrpresenting the underlying structure if the data: Principal Component Analysis (PCA); . Correspondence Analysis (CA); “Non-Metric Multidimentional Scalling” (NMDS); Principal Coordinate Analysis (PCoA)
