Learning outcomes
At the end of the course the student has skills on complex sampling plans. In particular, the student is able to: - design complex sample surveys - analyze and synthesize the information obtained in an advanced statistical perspective - identify and use the appropriate estimators for the inferential problem to be faced - evaluate and communicate the degree of uncertainty of the estimates obtained .

Teaching methods
The course consists of lectures and computer laboratory activities in R: lectures deal with methodological issues about the statistical tools listed in the course content, while computer laboratory sessions focus on the application of on specific case studies.
Assessment methods
There is a partial test at the end of the first lesson period on module 1 and a test at the completion of the course
The final grade will be the average of the two tests. The assessment is aimed at determining whether the methodological tools have been acquired to face a statistical analysis in the various phases, also with the aid of an adequate IT tool. The test (partial or total) is written and includes open and multiple choice questions both on methodological content and commentary on R.
Teaching tools
Slides, data sets and reports on statistical surveys
