Emphasizing applications over calculation, worldwide-bestseller STATISTICS FOR MANAGEMENT AND ECONOMICS, ABBREVIATED 10e vividly illustrates how vital statistical methods and tools are for today’s managers‚àíand teaches you how to apply them to business problems. Using a proven three-step “ICI” approach to problem solving, the text demonstrates how to IDENTIFY the correct statistical technique by focusing on the problem objective and data type; how to COMPUTE the statistics by hand, using Excel¬Æ 2013, or using MINITAB 16; and how to INTERPRET results in the context of the problem. Incorporating various functional areas of business, data-driven examples, exercises, and cases give you hands-on practice applying statistical applications used by marketing managers, financial analysts, accountants, economists, and others. Completely current, the ABBREVIATED 10e also includes updated figure and data tables, MindTap Reader, and access to Data Analysis Plus via the textbook companion website.
