Statistical Methods in Economics

This manual presents statistical methods, theoretical and practical, like statistical observations, group reports, averages and variations, analysis of time series, statistical estimations, hypothesis testing, index decompositions, and methods of studying the interrelations of economic events and processes. Every chapter contains practical tasks to help readers gain deeper knowledge and understanding of all problems in Statistics. The manual also provides graphic images of Statistics.

            It is intended for students specializing in economics, post-graduate students, teachers at institutions of higher education, business professionals and others.
