Statistics for management and economics
This worldwide best-selling business statistics text teaches students how to apply statistics to real business problems through the author's unique three-step approach to problem solving. Students 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. Keller's approach enhances student comprehension as well as practical skills. The book offers maximum flexibility to instructors wishing to teach concepts by hand or with the computer, or by using both hand and computer methods.
