| Purpose of the course | The aim is to introduce classical statistical concepts and methods with emphasis on methods used in epidemiology and public health. |
| Intended learning outcomes | After successfully completing this course students should be able to:
-define the concept of probability, laws of probability, and make simple probability calculations. (S2) -suggest a statistical distribution to describe a naturally occurring phenomonen and evaluate the appropriateness of the distribution given real data. (S3) -present appropriate descriptive statistics for an epidemiological study. (S2) -explain the difference between hypothesis testing and interval estimation and the relation between p-values and confidence intervals. (S3) -suggest an appropriate statistical test for a comparison of two groups, perform the hypothesis test using standard statistical software, and interpret the results. (S3) -estimate and interpret three alternative measures of association between binary exposures and binary outcomes and discuss the relative merits of each measure for a given research question. (S3) -explain the concept of confounding in epidemiological studies and demonstrate how to control/adjust for confounding using stratified analysis. (S2) -explain the basis of the linear regression model, fit a linear regression model using standard statistical software, assess the fit of the model, and interpret the results. (S2) Learning outcomes are classified according to Bigg's structure of the observed learning outcome (SOLO) taxonomy: (S1) uni-structural, (S2) multi-structural, (S3) relational, and (S4) extended abstract. |
| Contents of the course | The course introduces classical statistical concepts and methods with emphasis on methods used in epidemiology and public health. Topics covered include: the importance of statistical thinking; types of data (nominal, binary, discrete and continuous variables); data summary measures; contingency tables; graphical representations; notions of probability; probability models (distributions); principles of statistical inference; parameter estimation (mean, proportion (prevalence), incidence and ratios); concepts of confidence intervals and hypothesis tests; and a general introduction to correlation and linear regression models. |
| Teaching and learning activities | Lectures, exercises focusing on analysis of real data using the statistical software R, exercises not requiring statistical software, different group and individual assignments, literature review. |
| Compulsory elements | The individual written examination (summative assessment) is compulsory. |
| Examination | To pass the course, the student has to show that the learning outcomes have been achieved. Assessments methods used are group assignments (formative assessments) along with an individual examination (summative assessment). Students who fail will be offered a re-examination within two months of the final day of the course. Students who fail the re-exam will be given top priority for admission the next time the course is offered. If the course is not offered during the following two academic terms, then another re-examination will be scheduled within 12 months of the final day of the course. |
