内容説明
For Statistics courses found within Economics, Business, Marketing, or Statistics departments that are required for the Economics or Business major.
Newbold's strength has been its unerring accuracy and statistical precision. It is also at a mathematically higher level than most business statistics texts. This edition focuses on maintaining the statistical integrity of past editions while modernizing the text by integrating the use of statistical software, adding new examples and exercises (many with real data), and an emphasis on data analysis and interpretation of output. The fifth edition features both Excel and Minitab.
