Course Syllabus
Synopsis
This short course introduces students to biostatistics as applied to ecotoxicological studies. The basic principles and methods used in biostatistics are covered. This includes the technical qualifications necessary for exploring, analyzing and interpreting data from both controlled experiments, in particular standardized ecotoxicity tests, and field monitoring. Beyond conventional tests such as ANOVA and its variants, an overview of other less conventional approaches (e.g. GAM, Random Forest, t-sne, MDS) will be provided to broaden students’ statistical toolbox and ensure they make proper use of their data.
Aims
Investigating ecotoxicological data.
Objectives
At the end of this Unit, you should understand:
- Basics of experimental and sampling design.
- Main statistical approaches to monitor toxicants and estimate their effects on organisms.
- Assumptions and interpretation of statistical methods.
Key Skills Acquired
At the end of this Unit, you should be able to:
- Choose the most appropriate statistical method to answer a specific question.
- Use R software to analyse data.
- Interpret statistical results.
Syllabus
