Theory and Methods in Epidemiology and Biostatistics

Objectives

After the course students should be able to:

  • · To demonstrate a basic understanding of epidemiologic and statistical methods in a research project;
  • · To calculate, interpret and summarize the results of the descriptive statistics and exploratory data analysis for the purpose of scientific publications;
  • · To choose and perform statistical hypothesis tests (parametric and non-parametric), providing a critical interpretation of results and given a particular attention to the assumptions of each test;
