The concepts of probability and inference are introduced with emphasis on hypothesis testing and confidence intervals. Different types of analysis are discussed such as comparing two or several groups and analyzing relationships between variables. Parametric and non-parametric statistical tests are described and calculation of sample size is discussed. Epidemiological research articles will be discussed with focus on the statistical methodology. During the whole course theoretical parts will be illustrated with practical exercises for the students in a statistical software program.
