Prof. Siegel's book is a great introductory text for business graduates with little prior exposure to statistics. The text covers many of the basic topics in statistics and ties them nicely to real world cases and problems.
The book starts with a description of the basic constructs of statistics - data sets, distributions, and variability. IT follows with an introduction to probability and covers random variables. The text continues to cover statistical inference, confidence intervals, and hypothesis testing. Finally the book gets to regression and time series analysis and demonstrates several applications of the techniques covered.
The book comes with a CD that contains lecture presentations (very useful), all the data sets in the books (saves you typing), and an excel add-on called StatPad that provides many useful statistical tools.
Overall I think that this text is a good choice for MBA students and business professionals with little background in statistics. It is very user-friendly and is well grounded in business.
