Objectives
Objectives
Competences that should be developed: Mastery of most frequent statistical analyses. Autonomy to plan experiments and observation campaigns, and to analyze data. Capacity to choose the analysis that is most adapted to the data in study.

Teaching methodologies
Teaching methodologies
The student is put in a real situation: real data to analyze, total freedom in the choice of the analysis to try and develop his capacity to choose the most apropriate, information availability similar to the situation a scientist would know in the laboratory.

Ensino presencial com aulas teóricas e teórico-práticas: As aulas teóricas são aulas magistrais com
frequência voluntária seguindo o programa definido e de acordo com os objectivos da disciplina. As
aulas teórico-práticas são aulas tutoradas, orientadas por um docente, de frequência obrigatória
destinadas a aplicar a dados reais as técnicas descritas nas aulas magistrais. Requisitos para
aproveitamento final:
1) Avaliação contínua por 2 frequências (90%) e assiduidade (10%) (classificação total - média
ponderada - igual ou superior a 10 valores), com todos os documentos autorizados e com apoio
informático. Ou 2) Exame teórico-prático no final do semestre com o peso de 100% (classificação igual
ou superior a 10 valores), com todos os documentos autorizados e com apoio informático. Isenção de
repetir uma das 2 componentes teórico-práticas em caso de nota igual ou superior a 9,5 valores obtida
para esta componente em avaliação contínua ou exame final anterior.Presential teaching with theoretical and theoretico-practical classes: Theoretical classes are lectures of
facultative attendance that follow the defined syllabus and respect the objectives of the discipline.
Theoretico-practical classes are mandatory classes under the guidance and orientation of a teacher and
are intended to practice techniques described in theoretical lectures with real data.
Requirements to pass the discipline:
1) Continuous evaluation by 2 midterm exams (90%) and class attendance (10%) (final classification
- weighted average - equal or superior to 10), with all documents allowed and computer provided.
Or
2) Theoretico-practical exame by the end of the semestre with a 100% weight (classification equal or
superior to 10), with all documents allowed and computer provided. Students with a classification of at
least 9,5 obtained for a theoretico-practical component at a previous evaluation (continuous evaluation or
previous examination) are exempted from repeating it.
