Learning Outcomes
Knowledge Upon successfully completing this course, students will be familiar with: • The main differences between the types of studies of comparing populations • The appropriate summary measure of variables for quantitative and qualitative data • The difference between a sample and the population from which it came • The characteristics of the normal distribution and the difference from the asymmetric distribution • The sampling distribution and the concept of standard error of the mean • The methodology of hypothesis testing, the concepts of p value, the level of significance and confidence interval, the types of I and II errors • The basic parametric and non-parametric tests through real examples in the health and life sciences • In which data can be applied the survival analysis and how to conduct such an analysis Capacities The course participants upon completion will be able to: • Understand and compute the descriptive statistical measures that appear in the medical scientific articles • Formulate and interpret graphs appropriately • Calculate association measures such as mean differences, risk differences, relative risks, odds ratios and incidence rate ratios related reason and impact-rates • Calculate the appropriate sample size of a survey • Use the fast-growing and evolving R software as a tool for statistical analysis and the creation of elegant graphs
