This course provides with a comprehensive review of some basic mathematical and statistical methods and stresses their practical applications in business and economics. The course will equip the student with quantitative skills and will also provide a good foundation for addressing typical problems that arise in business. To an extent necessary to develop correct understanding of the topics, this course incorporates analytical and theoretical sections. The course focuses on statistical analysis of data and introduces concepts as sampling, hypothesis testing, regression analysis, probabilities, and decision analysis. Thus, solid basis is built for immediate practical implementation and as well for more profound studies of quantitative analysis, quantitative decision-making or other formal manipulation with business data.
