Theoretical sessions. Lectures are used to present concepts, explore examples and solve problems. Assessment: Task I (individual) – Importance of Statistics (two page A4 text); Task II (groups of 3 students) – Random variables (two page A4 text and 10 minutes power point presentation); Exam (problem solution). Practical sessions. Use of computer tools in descriptive statistics and in statistical inference: spreadsheet and statistical applications (SPSS and WinBUGS). Tutorial files are given with protocol, data and expected results. Students (groups of 3) write a scientific report to develop and assess different skills (GS1-4). Several problems are solved regarding the taught subjects, what is assessed through a computer practical exam.
