''The 4th Edition of Applied Statistics in Business & Economics'' provides real meaning to the use of statistics in real world by using real business situations and real data while appealing students to know why rather than just the how. Four distinct objectives have been met to follow this premise: objective 1: Communicate the Meaning of Variation in a Business Context; objective 2: Use Real Data and Real Business Applications; objective 3: Incorporate Current Statistical Practices and Offer Practical Advice; objective 4: Provide More In-Depth Explanation of the Why and Let the Software Take Care of the How. The emphasis of the 4th edition remains the same: thinking about data, choosing appropriate analytic tools, using computers effectively, and recognizing limitations of statistics.
