Teaching Methods
Theoretical-practical lessons with computers’ use with the allocation of a data bases to each student at the beginning of the semester. Students must use them throughout all the period of learning. In the end the student must submit a report with the presentation of the data bases using the methodologies studied in the discipline.
Learning Outcomes
Overall objectives: Introduction to the programming language R and how to use data bases write programs and to demonstrate how statistical models are implemented and applied
Specific objectives: Topics include creating data, importing data, accessing subsets of data, exporting data, plotting and graphing, loops and functions. It also will provide a basic knowledge of R that would help master the elementary and more advanced statistical tools available in R.
Generic competencies: How to use quantitative and qualitative data information and how to organize it with R.
Specific competencies: Students will be able to import, manage and structure elementary and complex data files; to write simple program scripts for data analysis; to produce and use illustrative data plots; to carry out some important statistical tests characterizing the data; to use appropriate linear and non-linear models and interpret them correctly.
