Main themes
Topics to be treated - General framework of inference in finite population; population, sampling, statistics for the inference based on experimental data, linear homogenous estimation: elementary units, complex units. - Sampling with unequal probabilities: Hansen-Hurwitz and Horvitz-Thompson estimators, for the particular case of simple random sampling. - Estimators improvement through auxiliary information: ratio estimator, regression estimator - Sampling from complex units: stratified sampling, cluster sampling, two stages sampling. - Sampling from biological populations: basic issues in sampling, estimation of the population size.
Learning outcomes
 At the end of this learning unit, the student is able to : 1 Objective (in terms of abilities and knowledge) This course aims at providing the student the basic knowledges on the sampling methods, with a particular, but not exclusive, emphasis on sampling from (finite) human populations. At the end of the course, the student should be able to correctly designing a simple survey and analysing the results.
Content
General framework of  inference in finite population :
• Techniques of random samplings and estimators properties.
• Simple random sampling
• Stratified random sampling
• Uneven probability sampling
• Cluster sampling
• Multi-level sampling
Estimation improvement by use of auxiliary information.
Teaching methods
8 x 2 hours of masterful presentations and 2 x 2 hours of practical exercices on computer.
This teaching is designed to adapt quickly to health developments (face-to-face, co-modal or distance teaching). Students are encouraged to regularly check their class schedule on ADE as well as the information available on Moodle.
Evaluation methods
Written exam in session and/or individual project assessed on the project report and its oral defense.
Other information
It is essential to have taken and successfully completed at least one course in inferential statistics.
