This worldwide best-selling business statistics book teaches readers how to apply statistics to real business problems through the authors unique three-step approach to problem solving. Readers learn to identify the right technique by focusing on the problem objective and data type. They then learn to compute the statistics either by hand, using Excel, or using minitab. Finally, they interpret the results in the context of the problem. Kellers approach enhances user comprehension as well as practical skills.
