This course introduces data analysis techniques used in business decision making and policy making. Students learn to identify the necessary techniques for a given problem, and to carry-out the data analysis techniques, for both quantitative and qualitative data, in order to solve realistic business-related and policy-related problems. They also learn how to interpret and critically evaluate statistical information presented in the media, in government reports or in business advertisements. Exercises, problems and decisions are set up to be of particular relevance to a business and organisational environment and group exercises are used to build collaborative skills. No mathematical prerequisite is required.
