In the Statistics II course, students will learn and practice use and interpretation of elementary statistical methods for data processing and basic analysis of economic and social phenomena. The students will learn how to distinguish the situations and appropriate methods for given circumstances and types of data. A guidance to proper presentation and interpretation of the data and their results will be provided as well. Selected topics will be presented in the computing environments of MS Excel and Gretl.
