EXPECTED OUTCOMES The research completed during my professional leave will result in a business statistics manual for use by students and practitioners. It will hopefully aid students in their study of this difficult subject and improve their performance in class. The attrition rate in undergraduate statistics classes is higher than it should be. It is the objective here to create a supplement that will help the marginal student pass both undergraduate and graduate statistics classes. In addition, it could be used as a quick reference guide for practitioners such as graduate students and managers. The use of computer software will provide a realistic approach to an otherwise difficult subject. Thus, one of the by-products of this manual will be to illustrate how computer software such as SAS and MYSTAT are used to facilitate the understanding of statistics. Mini cases are provided in most chapters to demonstrate the application of these computer solutions.
