Learning outcomes

The aim of the course is to deliver skills related to usage of data analysis tools and tecniques both in descriptive and inferential statistics. At the end of the course the student will be able to use for basic tasks one of the most common data analysis softwares. Moreover, the student will know and will be able to critically apply the main tools for descriptive and inferential statistics for both the univariate and the two or more populations case. The lab activity is aimed at improving autonomy of the students about data management.
