Course objectives
The course is oriented on practical basics of data analysis and information technologies application in medicine. Highlighted topics are related to management of data of clinical trials and data storage in hospitals. The data analysis presented during the lectures goes from the descriptive statistics through principles of statistical testing, selected statistical tests for continuous and categorical data to basics of regression modeling and power analysis. All methods are presented using practical examples and common software (Statistica for Windows, SPSS). The subject provides basic knowledge a skills about computer's network. Main objectives can be summarized as follows: to understand the network terminology; to connect personal computer to Internet; to use network services; to reduce risk of lost of data or secret information.
