Data Processing Technologies in Agro-Industry
Objectives
At the end of this course the student will have acquired knowledge, skills and abilities to:
- Understand a technical report where the information presented result from a statistical analysis and/or spatial modeling;
- Being able to synthesize information from a qualitative and quantitative dataset, in particular the interpretation and drawing of conclusions;
- Understand the bi-or multivariate relationships between variables of a dataset, and analyze redundancies and gaps of information;
- Distinguish the various sub-populations of a sample, and use the best tools for the generation of sub-sets of data;
- Generate estimated images of a continuous property locally sampled in the study area.
- Apply data analysis tools in R platform, including importing data, graphical view and the output of reports.

Teaching method
Theoretical and practical sessions of two hours each: i) theoretical lectures with powerpoint ii) practical classes in the computer room. The theoretical explanations are suported with practical examples related with the master course. The classes are based on problem solving, taking as a starting point realistic datasets that reproduce some of the situations that future professionals will work.
Evaluation method
The evaluation is preferably of continuous type but alternatively can be made by classical exam. Two written tests for methods (representing 25% + 25% of the final grade), and a report made by groups of two students with a resolution of the practical problems worked in class practices (remaining 50 %) will be developed for the continuous assessment option. Alternatively, students have a final theoretical examination where the grade of the theoretical component tests can be also improved. Frequency is obtained by presence in 2/3 of the practical sessions.
