Not applicable.

It is intended that students achieve in the curricular unit of non-parametric statistics the learning outcomes:
a) identify, when faced with data incompatible with parametric analysis, which statistical tests are appropriate for one sample;
b) acquire knowledge about different statistical tests to compare populations on the basis of independent or paired samples;
c) acquire knowledge about measures of non-parametric association.

Evaluation Methodology
- Continuous assessment: three written midterm tests during the semester (graded 0-20) with no minimum mark required. An average mark of 10/20 in continuous assessment is required to be exempted from exam.
- Final assessment: summative exam
