Today's managers need to understand data in order to make effective decisions. This course emphasizes the usefulness of data to a variety of business problems. It covers a variety of statistical tools including correlation, inference, and prediction, with an emphasis on regression analysis. This is not a course in “pure” statistics but rather about understanding and effectively using statistical methods and models for managerial decision making. It draws on real life examples and our own experience to provide students with the ability to use data to inform decisions. Building on what you have learned in the Foundations term, we emphasize the difference between what the data say and what the data mean. The objective is for students to leave this course with a better/an improved understanding of what statistics can (and cannot) do to help their business.
