Objectives: the students will develop and acquire the insight, tools and skills needed to be educated users and consumers of biostatistics. They will recognize data types, and correctly identify the statistical methods appropriate for analysis of a given clinical dataset. They will understand the basic concepts of statistics, including elementary probability theory, sampling, estimation, confidence intervals, and hypothesis testing. They will be able to conduct graphical and numerical exploratory data analysis using SPSS, and to perform statistical analyses, including comparative tests of categorical and continuous data.
