Full Description
Business Statistics teaches you skills that you can use throughout your career. It illustrates how vital statistical methods and tools are for today's managers and analysts, and how to apply them to business problems using real-world data. Statistical data analysis is the backbone of sound business decision making, and finding the right tool to analyse a particular business problem is the key.
The book shows you how to analyse data by focusing on the kind of problem you face, the type of data involved and the appropriate technique for solving the problem. It also includes data-driven examples, exercises and cases that cover how marketing managers, financial analysts, accountants, economists and others use statistics.
