Teaching language

Suitable for English-speaking students


This unit aims to empower the students with theoretical foundations and practical approach to basic statistical methods used in clinical research, assessment of technologies and health service research. After this course unit the students should be able to: identify the correct statistical methodology for data analysis; apply these methods using statistical software; interpret the results of the statistical methods

Learning outcomes and competences

At the end of this course, the students should be able to characterize different types of data and variables; computerize and process the data ; check for errors; describe graphically data; describe data with summary measures; apply basic techniques of statistical inferences ( point and interval estimation and hypothesis tests) and to apply a simple linear regression model. Students should also be able to criticize the statistical analysis of scientific articles published in the literature in Health Sciences area.

Working method
