The need for quantitative analysis in business becomes imperative because of the growing complexities of analytical problems in this area. Over the year there has been a present difficulty of clearly understanding and solving analytical problems by the people in the field due to their inability to develop models for handling such problems. It could be because their training emphasized acquisition of skills and their utilization with less attention to quantitative analysis. The presentation in the book is orderly, and grows with increasing demand for computational knowledge and understanding. It requires a basic knowledge of mathematics and statistics for its understanding. This book is written to meet the needs of students in universities and polytechnics offering business statistics and allied courses. It also satisfies the needs of postgraduate, research fellows and other researchers in the field of business statistics.
