内容説明
A comprehensive introduction to Business Statistics for students with a background in high school algebra. Extensively revised, the Seventh edition better prepares today's business students to think critically about reported data and to use appropriate statistical methods to make good decisions. Greater emphasis has been given to interpretation of computer output (Excel, Minitab, SPSS, SAS) over manual calculation. Six new, real cases make use of extensive data sets that are packaged with the book and a new Internet Lab feature connects students to the future. The supplements package has been extensively revised to include an Annotated Instructor's Manual, a PowerPoint Lecture tool, and a free Excel supplement for those seeking step-by-step instruction.
