Epidemiology

• Summary of the laws of probability distribution and some of the most important theoretical results.

• The process of Statistical Inference: Estimation of parameters. Application to biosciences.

• Statistical tests of association between categorical variables (Fisher’s exact test, chi-square test, McNemar’s test).

• Parametric and non parametric tests for comparing two or more independent samples (Mann-Whitney and Wilcoxon tests; ANOVA, Kruskall-Wallis and Friedman tests; L-Page and Jonckheere trend tests).

• Diagnostic tests and statistics in clinical trials. Odds Ratio.

• Tests on the correlation coefficients. Relation with linear regression.

• Applications of data in areas of health sciences and environmental issues.

• Topics for using a software (Excel) in supporting the resolution of problems

E-learning

Continuous assessment is privileged: 2 or 3 digital written documents (e-folios) during the semester (40%) and a
presence-based final exam (p-folio) in the end of the semester (60%). In due time, students can alternatively choose to perform one
final presence-based exam (100%).
