The main topics that will be covered are: 

• Experimental design to test one-to-one relationships 
• Isolating relationships from a complex context 
• Disturbances in field and on-farm experiments 
• The fragmentation of knowledge within experiments and institutions 
• Short and long-term experiments

Mathematical foundations will not be the core of the course; however, applications based on the analysis of datasets using JASP and R will be covered during the labs.  The evaluation will be based on quizzes and preparing a glossary.

It is recommended that students interested in the class have already taken a course of basic statistical methods (experimental design is not necessarily but a course on descriptive statistics is required) and have some experience with the Statistical Language R. 

The main topics that will be approached are: 

• Refresh of probabilistic distributions
• Bayesian inference,
  • Linear models 
  • Model comparison
• Application and introduction to Markov chain monte Carlo (MCMC)
