Applied Statistics for Business and Economics: An Essentials VersionEssentials of Business Statistics presents basic statistic concepts, including descriptive statistics, probability, and elementary inferential statistics in a student oriented style. All concepts are developed with support of unique three part examples: problem, solution, and interpretation, which give students the full picture. Applications are drawn from all areas of business and economics. This book is a refocused and shortened version of APPLIED STATISTICS FOR BUSINESS AND ECONOMICS 2/e by Webster. This briefer book concentrates on the core topics in business statistics. It is important to retain 2/e Webster users by presenting this 1/e as a "shortened" book. It is also very important to present it as a "new" alternative to the Mason level market, to replace any brief text, e.g. Mason, Levin/Rubin, Mann, Trioloa/Franklin and Anderson/Sweeney/Williams Essentials. |
